What extension cord is needed for a lawn mower

Extension type

• household. the simplest and most affordable. The socket strip can be equipped with a power button. this is the maximum functionality for this type of device. Grounding may or may not be. The length of the wire varies from 1.5 to 10 m, the cross section is from 0.75 to 1.5 mm, which determines the maximum power of simultaneously connected devices, but we will talk about this later. Conventional extension cords can be connected to each other, but they have no short circuit protection;
  
• surge protectors are advanced extension cords that are equipped with additional options. The contactor protects against overvoltage, the filter choke. against high-frequency noise, the varistor. dissipates impulse noise. Some models have 1 or 2A USB ports for charging gadgets. Surge protectors protect equipment, but they also cost enough, and are larger in size than conventional extension cords;
• garden extension cords are similar in design to household extensions, but protected from moisture. These can be safety shutters, circuit breakers or fuses. Such devices are distinguished by a long wire. from 20 to 100 m, can be equipped with a pin for easy attachment in the ground. The only drawback of such extension cords is their size and inconvenience in storage.

For most of you, an ordinary household extension cord is suitable, but they are also different, therefore, first of all, you need to answer yourself a number of questions:

• What is the distance from the outlet to the technique?
• What equipment will be connected, what is its power?
• In what conditions will the extension cord be used?
• What additional functions should the device have??

In fact, the answers to all these questions are the main parameters for choosing an extension cord for the home.

Length of cable

The parameter that attracts attention in the first place is the length of the cable. The longer the wire, the more freedom the user gets, because you can be at a sufficient distance from the outlet. When it comes to garages, terraces and summer cottages, this is priceless.

Remember that the longer the cable, the more power is lost, and if you connect a poor-quality or defective product, overheating may occur, and then the cable may burn or short circuit.

An overly long cable will be difficult to work with when the entire length is not required. We’ll have to wind it up, but at the same time it is worth remembering that the device can withstand the rated load only with the unwound wire. The manufacturer must indicate the maximum current with coiled and uncoiled cable.

At a construction site and in a garage, when an extension cord with a wire length of up to 20 m is purchased, it is better to use models equipped with a reel for reeling, but here you should be extremely careful. The fact is that when powerful equipment is operating, the wire will heat up, therefore it is better to buy extension cords with fuses. they protect against overload.

At home, when connecting powerful equipment, it is better to unwind the wire to ensure the best heat dissipation. It is believed that heating the cable up to 65 0 С is permissible, but just imagine what could happen if the turns of such a heated wire touch each other! The insulation will begin to melt, and there it is not far from the circuit.

On sale you can find devices with a wire length from some 0.5 m to 50 m and even more. The optimal length of the cable in the extension cord for domestic conditions is from 3 to 7 m.

Cable type

The type of wire is selected depending on the conditions in which the extension cord will work. Among the most common options are:

• PVA. the wire has a plasticized PVC sheath, copper conductors, round cross-section, is inexpensive, which affects the final price of the extension cord. The material is afraid of negative temperatures, dulls in the cold, and is also prone to abrasion. For domestic conditions, when the extension cord is not particularly pulled or frozen, this type of cable is perfect. Another disadvantage is sufficient massiveness, but it becomes critical when the cross section of the core is more than 2.5 mm2;
• Ball screws are used much less often, they have a flat cut. Due to the thinner insulation, the cable takes up less space. Suitable for living conditions, but under heavy loads, for example, at a construction site, it may not withstand and become unusable;
• KG (flexible cable) is suitable for harsh conditions. The core insulation and the cable sheath are made of rubber. Such a cable can withstand frost and heat, is resistant to mechanical stress, therefore, for difficult building conditions, this is the best option. However, such a wire should not be left in direct sunlight for a long time.

Wire size and maximum load

These two parameters are in direct proportion to each other: the larger the cross-section of the wire, the greater the load it can withstand. A simple analogue is the diameter of the water pipe. The more consumers, the larger the pipe must be so that everyone has a normal head.

Extension cords are made from standard wires, therefore the following cross-sections are possible:

• 0.75 mm2. designed for current up to 6A or voltage 1380 W. An excellent option for lamps and chargers, as well as modern TVs. they have a low power;
• 1.00 mm2. conducts 10A current, voltage 2300 W. Suitable for connecting not particularly powerful household appliances and tools
• 1.5 mm2. designed for a current of 16A, a voltage of 3680 W. Can be used with a washing machine, heater, any household construction equipment;
• 2.5 mm2 and more. extension cords required at a construction site and in industrial conditions are suitable for connecting powerful devices and equipment.

For rough calculations, you can use the following rule: 1 mm2 wire cross-section withstands a current of 10 A.

There are even extension cords with a core of 0.5 mm2, but it is strictly not recommended to include something more powerful than a table lamp in them. For home conditions, it is best to take a device with a wire of at least 1.5 mm2, so that it is a more or less universal device with protection from fools, since there will always be someone who does not look at the maximum load and connect a powerful heater to the extension cord.

Extension cords with a wire of more than 50 m must have a cable with a cross-sectional area of ​​at least 2.5 mm2.

Information about the cross-section of the cable can be found on the wire itself. it is marked accordingly. As a rule, the outer diameter of the wire indicates the cross section, but there are exceptions. One thing is clear. if a thin cable leads to the outlet block, then it is better to connect low-power electrical appliances.

First, think about what devices you are going to connect, and then go buy an extension cord. We recommend taking with a margin, since in the future more powerful devices may also be included in the list of connected devices. Please note that if the extension cord withstands 10A, this does not mean that a 10A device can be inserted into each outlet. It is about the total load.

What happens if you exceed the permissible load? The wiring may heat up and begin to melt, burn out the connection points of the wires, as a result. smoke and fires.

Number of sockets and plug type

The number of outlets varies from 1 to 4, or even up to 5-6. So many sockets are not made so that you can use 4-6 devices at once, but so that you can insert the plug and not remove it for a long time. Free nests still remain. Thus, both the extension cord and the wire of the electrical appliance will last longer.

Don’t go chasing a lot of outlets. get the extension cord that suits your needs. If you are going to connect only one device, then it makes no sense to take an extension cord for 4 sockets.

Pay attention to how the plug-in contacts of the sockets are located. The most convenient location is diagonal. In other cases, it can be problematic to connect two devices to adjacent sockets.

Have you examined the outlet block? It’s time to take a look at the extension plug. Give preference to molded forks, which are more reliable and safer. In addition, such forks are more difficult to manufacture, so it will be more difficult to run into an artisanal extension cord in this case.

Earthing

Grounding is a useful option that will reduce the risk of electric shock when operating a faulty electrical appliance, as well as reduce the level of interference in equipment connected to the same network or located nearby. The grounding conductor is especially important when connecting a washing machine and refrigerator to an extension cord. True, grounding will be relevant only when the apartment is connected to the ground loop.

Product design

The plug is connected to the mains, and the plug of the lawn mower is inserted into the socket at the end of the wire

Cheap extension cords are made coiled into a coil or on a frame reel, but it is convenient to use them only when the length is no more than 8–10 m. Both types are equally inconvenient because they begin to twist during unwinding and unwinding, and this leads to their tangling. Much more convenient extension cords for lawn mowers on a reel. When unwinding and winding them, the reel itself rotates, and not the cable around the reel, so twisting is excluded.

As a rule, the coils are made of plastic, less often of steel. There is no difference, the main thing is that they rotate freely on the axis. The structure is assembled on a metal or plastic frame, which is installed near the home power outlet, where the extension cord for lawn mowers will be connected. On the reel, in addition to the input plug, there is a handle for easy winding, sometimes an overload protection button. Unwind it by simply pulling on the end of the extension cord where the output socket is fixed.

Several electrical appliances can be connected to such an extension cord, but an additional extension cord is required to connect the mower.

There are also other design extensions for reel mowers. Their cord is unwound from the side of the input plug, and the coil itself is located close to the place where the work is being done. It usually contains several sockets, a built-in switch, an overload protection button, and a voltage indication light.

The multi-position outlet is convenient when you need power for more than one consumer at once. But in order to connect to it an electric tool with a short mains wire, you will need an additional extension cord, 5-10 meters long, however, it is no longer a reel.

How to choose an extension cord for a lawn mower: recommendations and tips

Gasoline technology, of course, is good for giving, but the exhaust gases do not harmonize with the green riot of the surrounding nature. Electric cars, quiet and easy to operate, are just what is best for suburban estates. But on the site you cannot attach an outlet to each tree. A special extension cord is already required here. A lawn mower, grass trimmer, or any other gardening machine requires an electrical supply that can provide the most powerful tool expected to be used in a given area.

Maximum power

There will be a little theory, but omitting Ohm’s law and “complex” calculations, we will be satisfied with empirical data, because our goal is just to understand how to choose an extension cord for a lawn mower, based on its power consumption.

Among the parameters of the cable, its cross section is important to us. The permissible overheating at the maximum transmitted power depends on it. Although the obtained value does not coincide with the passport data of a particular cable, in practice, the conductor cross-section in mm² is simply multiplied by 10 and this number is taken as the maximum permissible current. And the power in watts is already calculated by multiplying the voltage of the 220 volt network by the current in amperes. The result is a table like this:

• 0.75 mm² corresponds to 7.5 A, or 1650 W, for tools up to 1.5 kW with a small margin.
• 1.0 mm² corresponds to 10 A, or 2200 W, up to 2.5 kW with a margin.
• 1.5 mm² corresponds to 15 A, or 3600 W, up to 3.5 kW with a margin.
• 2.5 mm² corresponds to 25 A, or 5500 W, up to 5.5 kW with a large margin.

Electric wire marking

For domestic electrical extension cords, several types of wire are used, but only 3 types are suitable for outdoor use:

• PVA. two- or three-core, for outdoor use, UV-resistant, service life is more than 6 years. Insulation: polyvinyl chloride (PVC) inner and PVC outer sheath. In the cold it hardens, can crack. Coloring is arbitrary. Decoding: P. wire, B. PVC insulation, C. connecting.
• KG and KG-HL. two- or three-core, for outdoor use, service life is more than 4 years. Insulation by layers: polyethylene terephthalate (PET), rubber, PET, rubber. Increased resistance to mechanical stress, compression, bending. The color is black, remains soft in the cold, especially the CL modification is cold-resistant (up to 60 ° C). It is advisable to protect from sunlight. Decoding: KG. flexible cable.

If the extension cord is grounded, then the cord is three-core, and its marking should have the number “3”. Example. PVA 3×1.5. designation of a 3-core wire.

Which one to choose depends on the expected operating conditions. Theoretically, it is better if the cord is orange. it is clearly visible in the grass. But, practice shows that the frequency of damage to it by a lawn mower or trimmer does not depend much on whether it is black or orange. A person concentrating on work does not notice him, even if he is bright. Therefore, the choice of color is rather an aesthetic issue. However, the cable of the KG brand is more reliable, but it is produced only in a black version.

Plug connection elements

Garden equipment usually requires a single-phase power supply, respectively, to connect to the mains, a European plug with a 5 mm diameter pins is used (for the Russian one. 4 mm). There must be a corresponding socket.

Only three contacts are used: “phase” and “neutral” with a lead to the pins, as well as “ground” in the form of plates on the sides of the plug and socket. The “earth” contact must be connected to the earthing line of the household power supply, otherwise, during the operation of even such a low-power tool as a grass trimmer, there will be a potential equal to half of the power supply voltage between its body and the soil. That is, 220/2 = 110 volts (V). This will be felt especially strongly after the rain in leather shoes. not fatal, but the sensations are very unpleasant.

The plug and socket of the extension cord must be molded rubberized, protection class not less than IP44. They are available with rated currents of 10, 16 and 25 amperes (A). The conductive cord of the extension cord must end with a single outlet, as the multi-socket unit is too bulky.

Useful notes

Like any electrical equipment, extension cords are afraid of moisture. Working with them or leaving them in the rain is strongly discouraged. But if this has already happened, then the sockets and plugs should be well blown, then dried in a hot, dry room for at least a day. It is only possible to work on dew if the plug connection is guaranteed not to touch wet grass. Failure to comply with this rule leads to its complete failure or even to the fire of the extension cord.

If you need to supply electricity at a distance of more than 30 meters, then it is better to choose a thicker cable, since on a thin one, with a high consumer power, the voltage can drop significantly. But outside the city, it is often below par, so it may happen that the power tool will not be able to develop sufficient power or will completely refuse to work. The problem with low “rural” voltage can be solved by installing a 3–6 kW single-phase stabilizer in the house, for example, the ENERGY Classic 5000 or RIDER RDR 5000 brand. These inexpensive devices are capable of maintaining a constant 220V output voltage from 120V to 280V input.

When unwinding the cable, in no case throw it off the reel, otherwise it will begin to twist and it will be very difficult to bring it back to its initial state.

Plot size and extension

Garden power tools usually have a very short power lead. No more than 50-70 cm. Therefore, the outlet must reach any corner of the site, and before choosing an extension cord for a lawn mower, it is advisable to calculate its length based on the configuration and area of ​​the territory.

For example, the diagonal of a plot measuring 20×50 m will be approximately 54 m.Adding about 5 m in reserve and rounded to the nearest standard value, we get 60 m.But usually the point where the extension cord will be connected is not at the very edge of the plot. Therefore, it is better to measure all distances with a string, taking into account various obstacles, throw in 5 m of stock, and then round up to a larger value.

How to choose an extension cord on a reel for a lawn mower?

https://www.YouTube.com/watch?v=eU0BzmvTpwo The lawn mower reel extension is the perfect solution to make lawn mowing comfortable and safe. It is easy and quick to unwind and unwind to the desired length, convenient to store. Conventional extension cords get confused, problematic to unwind and even more difficult to unwind.

It is not rational to purchase a separate extension cord for a lawn mower. You need to think about with what devices and in what conditions it will work. Therefore, when choosing an extension cord on a reel for a lawn mower, you need to consider several factors and characteristics.

Main characteristics of extension cords

You can choose an extension cord according to various parameters and characteristics. The most important of them are:

• extension length;
• wire diameter;
• number of wires in one sheath;
• the number and type of outlets installed;
• type of insulation;
• extension cord color.

To determine the length of the cable, the easiest way is not to rely on mathematical calculations, but to measure the distance from the connection point to the most distant point of the section. This can be done with an ordinary cord, laying it along the territory of the site without tension, and then measuring its length. It should be borne in mind that in different years the location of the beds, bushes, flower beds can change. Therefore, the cable length must be taken with a margin.

The stock should not be large. The entire cable heats up during operation, but its part wound on a coil does not cool well, so the insulation of this part quickly loses its quality. And the cost is increasing.

You also need to consider the way the mower is connected to the reel. Many mowers are supplied with a short cable to connect to the reel. It is clear that working on a large area with such a connection will not work. Another adapter must be used between the reel and the mower. Usually its length is 5-10 m. By this amount, you can reduce the length of the extension cord on the reel.

The wire cross-section is determined based on the power of the connected devices. The power of modern wheeled lawn mowers ranges from 1000 to 2500 watts. The minimum permissible diameter of one conductor for a power of 1000 W is 0.75 mm, but for reliability it is preferable to use a wire with a cross section of 1 mm. For a 2500 W mower, a cross section of 1.5 mm will be optimal. The use of wires with a smaller cross-section leads to loss of power, wasted energy, heating of the wires and, as a result, destruction of insulation.

When buying, you should pay attention to the marking: it indicates the current value for which the wire is designed. This is the maximum allowable value and is given for a fully untwisted wire. If a part of it is in a wound state, the maximum allowable value must be reduced.

It is not known in advance which devices and what power will be connected, so it is better to choose the wire cross-section with a margin.

Usually extension cords on a coil have 3 wires: phase, neutral, ground. Most modern electrical devices are designed to work with a ground connection. But in some houses, especially summer cottages, grounding may be absent. Therefore, it is pointless to purchase an extension cord with 3 cores in this case.

The reel can be fitted with open and closed sockets. The second type is preferable, since the extension cord can work in high humidity conditions, stay in the rain. If you intend to use it not only for working with a mower, then the more sockets, the better.

The type of insulation is determined depending on the operating conditions.

The most popular and relatively cheap is the PVA-sheathed cable. You can work with it at both negative and positive temperatures, but over time, due to temperature differences and exposure to sunlight, microcracks appear in the insulation.

If you plan to use an extension cord at low temperatures, it is better to use an all-season extension cord marked KG. It is more expensive, but the cable is better protected from mechanical damage, microcracks do not appear in the insulation.

The color of the wire is usually black, but orange is preferred. It is clearly visible both in bright sunlight and in the shade of a garden in the evening. The black wire is poorly visible, it is easy to hit it with a mower and cut it off, and a short circuit usually occurs.

Recently, automatic reels have been gaining popularity. They are fastened to the ground using clamps. Due to the tension, the wire is unwound, the length of its working part increases, and when the tension is released, it is automatically wound on the spool.

Some models are equipped with automatic shutdown in case of overload or overheating.

When choosing an extension cord for a lawn mower, you should not save. Convenience and safety of work depends on its quality.

Good to know

• PVA 2×0.75: wire in a plastic sheath, 2 cores, cross-section 0.75 mm, without grounding;
• KG 3×1.0: rubber-sheathed wire, 3 cores, cross-section 1.0 mm, with grounding.

The permissible temperature for heating the cable is 60 ° C. At higher temperatures, the insulation loses its properties.

The permissible current value in a single copper wire with a cross section of 1 mm is 10 A. If there are 2 or more wires in one sheath, the maximum current should be divided by 0.8 or the cross section must be multiplied by 1.25.

To calculate the current consumed by the lawnmower, divide its power by the supply voltage.

In hot weather, the resistance of the wire increases. This leads to a decrease in the power of the mower and an increase in energy losses.

User’s manual

If desired, you can permanently fix the extension cord before use. for this, the coil design is equipped with two mounting holes. Buying a chainsaw is a rather difficult task, because it is not easy even for a professional to decide among the many variations of proposals. The Carver chainsaw is quality, reliability at an affordable price. There is no longer such a stylish and attractive tractor as MAZ-541, which “lived” only on the territory of airports, and the number of MAZs of this model produced is only 3 pieces. By clicking on the link, you will learn a lot of interesting things about this special airfield tractor. With the help of the cultivator, you can easily and at high speed plant in the soil of various crops, as well as carry out various other procedures. Here you can see the Patriot cultivator. Install the spool in a suitable location, mark the future location of the fasteners through the holes, drill the indentations, and secure the extension drum with bolts or other suitable fasteners. To turn on the extension cord, you must connect its plug to a stationary power outlet. The auto reel has an auto unfolding-folding function. Unwind the cable to the desired length. After each half-turn of the cord, it is secured.

How to choose a lawn mower or grass trimmer extension. Every year in May June we open the “summer” season, and we are faced with the question. Which extension cord is suitable for a lawn mower or grass trimmer. Let’s try to figure out how to buy a garden / country extension cord for a grass trimmer / lawn mower and other garden technology Decide on the length of the extension cord. The length of the extension cord must be sufficient for your area. “” A little stock. Remember. Excessive extension cord lengths can affect your budget. Calculating the approximate length of a lawnmower extension cord is straightforward. Let’s take an example: Your site has a rectangular shape with sides equal to 20 meters and 30 meters, respectively (classic 6 acres). Applying the formula A2B2 = C2 where A and B. are the sides of the plot. and C is the length of the section along the diagonal. In our case, the length of the diagonal is 36.06 meters. We will take this value as the approximate length of the extension cord. By rounding up to 40 meters (the closest size of the standard extension cord model), we will get the required extension cord length, taking into account bends and turns, if buildings are located in different corners on your site. and each has the ability to connect an extension cord. then you can round the length downDetermine the power of your lawn mower or grass trimmer. the cross-section of the extension cord will depend on this. (The power can be viewed either in the product passport. or on the nameplate attached to the mower body. As a rule, the power of the grass trimmer does not exceed 2.0 kW (2000 W). ) no more than 4.0 KW (4000 W). Accordingly, for each power, you can (and should!) choose the correct cross-section of the extension cord. For trimmers, this is: 0.75 mm. enough for power up to 1.5 KW 1.0 mm. with a small margin for power up to 2.0 KW 1.5 mm. with a good margin for power up to 3.5 KW For wheel lawn mowers with power from 0.9 and below up to 2.5 KW, the wire cross-section will be: 0.75 mm. at a minimum of 1.0 mm. with a small margin of 1.5 mm. with a margin For lawn mowers with a power of 2.5 kW and up to 4.0 kW, the cross-section of the extension cord must definitely be at least 1.5 mm. Decide on the grounding of the extension cord. If you require an extension cord with grounding, then select the extension cord with the number “3” in the name of the extension cord after the wire brand. Example: Extension cable “Atlas” on a coil of 30 m KG 3×1.5 mm “KG” is a wire brand. Read more about wires in the article: Types of extension cables. “3” stands for. that the extension cord has 3 cores (ie PHASE. NEUTRAL. EARTH), respectively, the extension cord has a grounding conductor. “1.5”. indicates the wire sizeAfter you have decided on the length and power of the extension cord. Decide on the design of the extension cord: This is usually either: A lawn mower extension cord on a plastic reel of the Atlas series. You can read about the device of these reels in the article: Selecting reels for an extension cord. For low-power trimmers and lawn mowers, we offer a budget option. extension cords on the frame of the “Avangard” series General recommendations for choosing an extension cord for a lawn mower or a grass trimmer. an extension cord for a lawn mower / grass trimmer should have one rubberized outlet, since if there is a two or three or more outlets will make it difficult to connect the mower / grass trimmer and will interfere with your workRecommend to use a lawn mower extension cord with orange colored wires. as this color is more visible on grass and ground. which will protect you from accidentally cutting the wire with the lawnmower or trimmer while working. (In the manufacture of our extension cords, only orange wire is used. With the exception of extension cords with the KG brand wire). since grass mowing takes place mainly in the summer. at a temperature. it is more practical to choose a grass trimmer extension cord with PVA wireIf you plan to use an extension cord at low temperatures. for example with a snow blower or for other work, we recommend extension cords of the “Parity” series with a wire of the KG brand.

What section of the extension is needed for a lawn mower or grass trimmer for 1.5 or 2 kilowatts?

What extension is needed for a lawn mower or grass trimmer for 1.5 or 2 kilowatts? How Extension Length Affects Lawnmower or Grass Trimmer Performance?

Answers:

Like any electrical equipment, extension cords are afraid of moisture. Working with them or leaving them in the rain is strongly discouraged. But if this has already happened, then the sockets and plugs should be well blown, then dried in a hot, dry room for at least a day. It is only possible to work on dew if the plug connection is guaranteed not to touch wet grass. Failure to comply with this rule leads to its complete failure or even to fire the extension cord.

When unwinding the cable, in no case throw it off the coil, otherwise it will begin to twist and it will be very difficult to bring it to its initial state.

About manufacturers

Since extension cords are not a very complicated thing, their production was mastered by several Russian enterprises. The most successful of them is Electrokontakt LLC, which has the most extensive range of products of very good quality of its own production. Lesser known companies that produce extension cords for garden work: SUNTEK, Enkor, Electraline, Svetozar. The quality of their products is also acceptable, although the range of some leaves much to be desired. Of the imported extension cords, products under the brand GRINDA (China), AS Schwabe (Germany) have good quality. Special attention should be paid to the reel extension cords from the German companies Hugo Brennenstuhl and UNIVersal, equipped with the Bretec anti-twist system. However, in terms of price, all of them, including Chinese ones, having a slight advantage in quality, are unable to compete with Russian products.

Electric Lawn Mower Extension Cords

• The extension cord must be equipped with one rubberized socket. The presence of two or more outlets will create difficulties when connecting an electric lawn mower and will cause inconvenience in the process.
• For use in combination with lawn mowers, extension cords are best suited, the cord of which is colored orange. These colors are simply more visible on the ground, thereby minimizing the likelihood of accidental cable damage and related problems.
• Due to the fact that lawn care works are carried out mainly in the warm season, it is preferable to choose an extension cord with a PVA wire for use in conjunction with an electric lawn mower.
• If the extension cord will be used not only in conjunction with a lawn mower, but also to perform various works in the cold season, give preference to models with KG wires.

Good to know

• PVA 2×0.75: wire in a plastic sheath, 2 cores, cross-section 0.75 mm, without grounding;
• KG 3×1.0: rubber-sheathed wire, 3 cores, cross-section 1.0 mm, with grounding.

The permissible temperature for heating the cable is 60 ° C. At higher temperatures, the insulation loses its properties. The permissible current value in a single copper wire with a cross section of 1 mm is 10 A. What is important to know when choosing a grass trimmer for a summer residence. What is an extension cord for what. If there are 2 or more wires in one sheath, the maximum current should be divided by 0.8 or the cross-section must be multiplied by 1.25. To calculate the current consumed by the mower, divide the power by the supply voltage. In hot weather, the resistance of the wire increases. This leads to a decrease in the power of the mower and an increase in energy losses.

How to choose a lawn mower extension

How to choose a lawn mower or grass trimmer extension.

Every year in May June, we open the “summer” season, and we are faced with the question. What extension cord is suitable for a lawn mower or grass trimmer. Let’s try to figure out how to correctly and at minimal cost to purchase a garden / suburban extension cord for a grass trimmer / lawn mower and other garden technicians.

Your site has a rectangular shape with sides equal to 20 meters and 30 meters, respectively (classic 6 ares).

Applying the formula A 2 B 2 = C 2 where A and B. are the sides of the plot. a C. the length of the section along the diagonal.

In our case, the length of the diagonal is 36.06 meters. We will take this value as the approximate length of the extension cord. By rounding up to 40 meters (the closest size of the standard extension cord model), we will get the required extension cord length, taking into account bends and turns, if buildings are located in different corners on your site. and each has the ability to connect an extension cord. then you can round the length down.

-Decide on the power of your lawn mower or grass trimmer. the cross-section of the extension cord will depend on this. (The power can be viewed either in the product passport. or on the nameplate attached to the mower body.

Usually. grass trimmer power does not exceed 2.0 kW (2000 watts). and trolley lawn mowers (wheeled lawn mowers) no more than 4.0 kW (4000 watts). Accordingly, for each power, it is possible (and necessary !!) to choose the correct cross-section of the extension cord.

0.75 mm. enough for power up to 1.5 kW

1.0 mm. with a small margin for power up to 2.0 kW

1.5 mm. with a good margin for power up to 3.5 kW

For wheel lawn mowers with a power from 0.9 and below to 2.5 kW, the wire cross-section will be:

1.0mm. with a small margin

For lawn mowers with a power of 2.5 kW and up to 4.0 kW, the cross-section of the extension cable must definitely be at least 1.5 mm

General Guidelines for Choosing a Lawn Mower Extension or Grass Trimmer

-We recommend using an orange mower extension cord. as this color is more visible on grass and ground. which will protect you from accidentally cutting the wire with the lawnmower or trimmer while working. (In the manufacture of our extension cords, only orange wire is used. Except for extension cords with KG brand wire)

-since the grass mowing takes place mainly in the summer. at a temperature. it is more practical to choose a grass trimmer extension cord with PVA wire.

-If you plan to use an extension cord at low temperatures. for example with a snow blower or for other work, we recommend extension cords of the “Parity” series with a wire of the KG brand. about wires here: Extension Wire Types.

The presence of a power filter and a shutdown button

An important feature of using an extension cord for powering electronics is the presence of a power filter and a button for disconnecting from the network. A surge protector is a device for suppressing electromagnetic interference generated by your equipment on the mains supply. Their occurrence is due to the principle of operation of pulse converters and will not be considered within this article.

In addition to the filter, a varistor is installed in such devices, which protects the connected electronics from high-voltage surges and voltage surges, as well as a fuse and a button to turn off the power. It is convenient to use it by turning off the power to the equipment when you are not using it. This way you further reduce the risk of damage from power surges if you choose an extension cord with extra protection.

Section, length and type of cable

The main thing to check when choosing is what power or current the electrical extension cord can withstand. This information should be indicated on the packaging or determined by the product itself, now we will tell you more.

Sometimes people mistakenly believe that if an amperage of 16A is written on the outlet or plug, then the entire extension cord will withstand this current. not a fact! To select the appropriate amperage, some electricians use rules such as:

10 A per 1 sq. mm conductor cross-section

And this works in most cases, albeit with slight deviations. That is, an electrical extension cord with a cross-sectional area of ​​the cores:

• 0.75 sq. mm. suitable for 6 A;
• 1 sq. mm. 10 A;
• 1.5 sq. mm. 16 A;

Extenders of great length (from 25 or 50 meters, including those made in the form of a coil) are made with a wire with a cross-section of TPZH of 2.5 square meters. mm. Firstly, to reduce losses, and secondly, to make the product more durable.

But for everyday tasks, such as connecting a washing machine or for a heater, it is enough to choose an extension cord 5-7 meters long with a cross-section of conductive conductors of 1.5 square meters. mm.

An electric wire of the PVA brand is excellent for an extension cord. It has thick insulation, a circular cross-section, and a dielectric-filled gap between the conductors, which improves performance and resistance to damage. It bends well, but such a structure is quite dense and an electrical extension cord with 2.5 sq. mm turns out to be quite heavy and voluminous.

Such a wire is great for assembling an extension cord with your own hands. Electricians often use a flat cord of the SHVVP brand. It does not have too thick insulation, in comparison with the previous example, however, it is quite suitable for laying and constant work, while at a construction site it will quickly become unusable.

And for work in difficult conditions, it is better to choose an electrical extension cord, which is made of KG cable.

The thicker the wire, the easier it will transfer mechanical stress. But its thickness does not guarantee the same thick veins. Cheap products do not have markings on the wire at all. beware of them.

So, first of all, the choice of an extension cord occurs according to the power of the equipment that you will connect to it, and the distance from its installation to the nearest outlet.

Design of plugs and sockets, their number

The plug and socket design allows you to choose an extension cord with or without grounding. At the same time, it will be difficult or impossible to insert the plugs of Soviet electrical appliances into the version with grounding contacts and deep sockets. To connect not too powerful household appliances (up to 1 kW), the version with shallow sockets will be universal.

Structurally, forks can be cast and collapsible.

Cast forks will last longer, and collapsible ones will be replaced faster. When choosing an extension cord, take into account the fact that copies with collapsible plugs can often turn out to be counterfeit products, that is, the so-called samopal.

It is also important to choose the right degree of dust and moisture protection. For outdoor use, for example in a summer cottage for connecting a lawn mower or in a building for a welding machine, it is necessary to take into account the possible ingress of water drops. In this case, you need to choose an extension cord with the highest possible degree of protection, it is marked as IPxx, where xx are digits and the larger they are, the more protected the device. In the photo below you can see an example of a model with closed sockets.

Sockets can be from 1 to 4. Less common are models with 5 or more sockets for connecting a plug. Do not buy a carrier with 4 outlets if you know for sure that you need it for a specific device and you will not connect anything else. In this way, he will last longer and be safer.

Which is better for different conditions

Consider several typical cases when you need an extension cord and which one is better to choose.

Workplace connection. Usually in this case there is a set of equipment for which you need to provide outlets:

• For a computer. a system unit and a monitor or laptop.
• For speakers and printer.
• For modem or router.

In total, you need from 3 to 5 connectors. The power consumption of this set rarely exceeds 1, and even less often 2 kW (if there is a laser printer). Then you definitely need to use a surge protector, similar to the one in the picture below, but which one to choose?

The best manufacturers of extension cords for your computer:

• Pilot. sometimes filters are called by this word, because this company has been on the market for a long time and has recommended well.
• SVEN is a brand under which a range of additional equipment for PCs of good quality is produced.
• APC. also known for their uninterruptible power supplies.
• Defender is a Russian brand, good products are sold under it.
• Xiaomi. does not need Комментарии и мнения владельцев.

For a drill, it is best to choose a power extension with one outlet, because it will last longer, it is easier to pull it up on the wire when you are drilling the ceiling or holes for the cornices, and it is less likely that debris will be poured into unoccupied connectors and something will short out.

For a garage, a power extension cord on a coil with a length of 25 meters and a thick wire will be useful. It is suitable for connecting a small machine or welding inverter.

The same option would be a great solution for a summer cottage if you need to connect an electric grass trimmer or lawn mower. But keep in mind that you cannot overload the extension cords on the coil, because in such a design, the wire cannot be fully cooled when it is wound and its insulation can float.

For home, for example, for a TV and similar equipment, any model of suitable length and with the right number of connectors is suitable, because modern appliances consume a little electricity. Whereas for a hair dryer, it is better to choose an extension cord with 1.5 sq. mm.

For an electric stove, it is generally undesirable to use an extension cord and connect it directly to a circuit breaker and an RCD. But if we are talking about a small portable stove with one or two burners with a total power of 2-3 kW, choose an extension cord with grounding and a cross-section of at least 1.5 sq. mm.

Now you know how to choose an extension cord and which one is best for connecting household appliances, electronics and garden tools. We hope the advice provided helped you find the best option for your own conditions.!

Extension cord: which one to choose for carrying, self-winding for a lawn mower, which one is needed for a grass trimmer. what does a garden one consist of?

Electric lawn mowers are good for everyone: they are lightweight, mobile, relatively inexpensive, productive and environmentally friendly.

The only big drawback of such devices is the dependence on the electrical network, which causes many inconveniences if it is necessary to process a spacious lawn in the absence of a sufficient number of connection points (sockets).

You can solve the problem with an extension cord. After reading the information below, you will learn how the lawn mower extension cord works, you will receive recommendations for choosing the right device and its subsequent operation.

How to choose an extension cord

When choosing an extension cord designed for use in conjunction with an electric lawn mower for grass, you need to pay attention to a number of significant parameters and characteristics.

First, choose the optimal length of the extension cord. At this point, focus on the size of your site. Additionally add a couple of meters “in reserve”.

It is also not worth getting too carried away in this regard. with each additional meter, the cost of the extension cord increases significantly.

You can use the following diagram to determine the approximate length of the extension cord.

Given: a rectangular section 20×30, i.e. standard 6 ares.

Find the square of the diagonal of the plot by summing the squares of its sides. Next, you need to root out the resulting value to get the length of the diagonal. In the case of this section, it will be 36.06 m.

The nearest standard length of an extension cord is 40 m. We buy such a product. The stock will be used to compensate for turns, bends, etc. It is possible to round the estimated length downward only if stationary sockets are installed in different corners of the structure located on the site.

Secondly, you need to determine the appropriate cross-section of the carrying wire. To do this, you need to know the power of the lawn mower (indicated in the product passport or on the body). The power of simple electric trimers is usually no more than 2 kW, wheel lawn mowers. up to 4 kW.

In the case of trimmers, the recommended cable sizes are as follows:

• for a device with a power not exceeding 1.5 kW. 0.75 mm;
• 1.5-2 kW. 1 mm;
• 2 kW and more. 1.5 mm.

The cross-section of the extension cable intended for use in conjunction with a lawn mower with a power of more than 2.5 kW must be at least 1.5 mm.

Thirdly, it is necessary to resolve issues with the features of the grounding of the extension cord. If grounding is necessary (and its presence is highly recommended), buy a product that has the number “3” in the marking. As an example, we can consider the KG extension cable 3×1.5 mm from the popular Atlas brand.

In this case, “KG” indicates the brand of the wire, and the number “3” indicates that the extension cable consists of three cores, one of which is directly the grounding wire.

Fourth, you need to select the appropriate extension cord design. As noted, such products can be made on a reel or in a coil. The first option is the most preferable. The second is used mainly on an industrial scale and allows you to connect more powerful equipment.

Fifth, it is necessary to take into account a number of general recommendations for choosing an extension cord for a lawn mower:

• The extension cord must be equipped with one rubberized socket. The presence of two or more outlets will create difficulties when connecting an electric lawn mower and will cause inconvenience in the process.
• For use in combination with lawn mowers, extension cords are best suited, the cord of which is colored orange. These colors are simply more visible on the ground, thereby minimizing the likelihood of accidental cable damage and related problems.
• Due to the fact that lawn care works are carried out mainly in the warm season, it is preferable to choose an extension cord with a PVA wire for use in conjunction with an electric lawn mower.
• If the extension cord will be used not only in conjunction with a lawn mower, but also to perform various works in the cold season, give preference to models with KG wires.

Principle of operation

The principle of operation of an extension cord for a lawn mower for the end user is not much different from the mechanism of action of an ordinary network carrying: the device is plugged into an outlet, transferred to the required distance (unwound to the desired length), where the device is connected to it, in this case, a lawn mower.

By design, lawn mower extensions are classified into coiled and coiled products. The second option is the most popular and preferred.

In turn, the extension cords on the reel are also classified into 2 groups. Representatives of the first category look like a coiled extension cable, one end of which is equipped with a molded socket. Directly the coil and plug are located at the other end, located at the point of connection to a fixed outlet.

This design is very convenient to use. the user does not need to carry the coil itself, it is enough to simply unwind the wire. Thanks to the features of the housing, unwinding and reeling of the cable is done quickly and effortlessly.

The second type of extension reel is noticeably different from the model discussed above: here the reel is equipped with several sockets, allowing you to connect more than one device at the same time.

Metal and plastic can be used to make coils. The first option is more preferable and is characterized by improved indicators of durability and resistance to adverse external influences.

For use in combination with electric lawn mowers AL-KO, Gardena, Stig, Bosch Rotak 32, STIHL, Makita, Champion, reel extension cords of the first group are best suited, because in accordance with safety precautions, it is strongly discouraged to move the coil away from a stationary outlet.

Along with this, models made in a waterproof case are available for sale. if possible, use just such an extension cord for a lawn mower on a reel.

User’s manual

If desired, you can permanently fix the extension cord before use. for this, the coil design is equipped with two mounting holes.

Buying a chainsaw is a rather difficult task, because it is not easy even for a professional to decide among the many variations of proposals. Chainsaw Carver. quality, reliability at an affordable price.

There is no longer such a stylish and attractive tractor as MAZ-541, which “lived” only on the territory of airports, and the number of MAZs of this model produced is only 3 pieces. By clicking on the link you will learn a lot of interesting things about this special airfield tractor.

With the help of the cultivator, you can easily and at high speed plant in the soil of various crops, as well as carry out various other procedures. Here you can see the Patriot cultivator.

Install the spool in a suitable location, mark the future location of the fasteners through the holes, drill the indentations and secure the extension drum with bolts or other suitable fasteners.

To turn on the extension cord, you must connect its plug to a stationary power outlet. The auto reel has an auto unfolding-folding function. Unwind the cable to the desired length. After each half-turn of the cord, it is secured.

To roll the cable after use, pull on the cable until it is secured, then slowly roll the cable.

Automatic reels are characterized by a high traction force. Do not allow the cable to be rolled up uncontrollably. Hold the end of it and slowly guide it along the movement of the auto coil.

The reels of modern garden extension cords are equipped with mechanisms that provide protection against overheating during operation. As a rule, the color indication is the same in different models. So, if the LED glows red, this indicates that the overheating protection is on.

When the aforementioned protective system is triggered, the light will go out. In such a situation, the user must disconnect the extension cord from the mains. After a few minutes (when the extension cord has cooled down), the device can be turned on again.

Lawnmower reel extensions are maintenance-free. It is enough just to periodically clean them. The auto coil must not be energized during cleaning. To comply with this rule, remove the extension cord from the stationary outlet.

Cleaning the outside of the extension cord is done with an ordinary dry and clean cloth. Make sure that moisture does not get into the construction of the extension cord coil.

When using an extension cord, observe the basic safety regulations and precautions:

• do not disassemble the extension cord;
• do not use the product in rainy weather;
• do not use an extension cord in places with excessive humidity;
• do not allow moisture to enter the structure of the extension cord;
• do not use the extension cord in places with excessive dust, vibration, etc.;
• do not short the socket terminals;
• do not let children use an extension cord;
• do not plug appliances into the extension cord, the total power of which exceeds the maximum permissible for this appliance.

Now you know what a lawn mower extension cord is, how to choose and use it correctly. Follow the recommendations you receive and everything will work out in the best possible way.
