What tool is needed for electrical work. Electrician's Tools - A list of professional tools for home and industrial use. Wire connection tools

Consider what tool for an electrician will need in an electric installation work ah in power networks up to 1000 volts, as well as in household wiring electrical wiring.

The tool for an electrician, which may be needed when making repairs or installing electrical wiring, cannot be accurately determined, however, we will highlight the tool that is usually used in such work.

It should always be with the electrician:

• Measuring instruments for control ( control lamp, multimeter).
• Pliers.
• Side cutters.
• Adjustable type wrench, or socket wrenches.
• Screwdrivers.
• Torch.

Electricians-professionals may have another tool for themselves, which gives them the opportunity to speed up and make the job easier. Let's take a closer look at various tools for an electrician.

Checking tool for an electrician

First of all, the electrician must protect himself from impact. electric shock. It turns off the machine, or another device that de-energizes the power grid. Next, the electrician monitors the presence or absence of electricity with a special device.

Phase probe 220 volts

The most needed control tool is , or a probe. Such measuring instruments make it possible to determine the phase. This is required to connect electrical devices in accordance with the diagram.

The main part of all probes is made in the form of a screwdriver. Using such a probe for electrical installation is inconvenient and even dangerous. The plastic for its manufacture is fragile, the body cracks during operation, the metal tip bends.

A device that gives out much more information than an indicator screwdriver is called a multimeter. It allows not only to control the presence of voltage, but also to diagnose breakdowns, correct installation. Such a device is called differently: tester, tseshka.

There are many devices of this type in the distribution network, but they are not very reliable, often break down, and professional instruments have a high cost. The tester may fail, for example, when measuring a resistor, in a circuit section that is not disconnected from the power supply.

To make a choice of the device, you need to focus on the execution of the shape of the probes. They must have elasticity, flexural strength. And also, the body of the device must be of high quality, it is better if it has a rubber cover. The multimeter can measure both AC and DC voltage values, resistor values. There are other options that are rarely used.

Widely used are current clamps, which can measure the flowing electric current in the wire, without physical contact with the core of the conductor, without breaking the circuit.

Such a device is universal model. With it, you can measure the current, and by connecting auxiliary probes to it - AC and DC voltage, as well as resistance.

Megaohmmeter

This type of device contains in its design a built-in dynamo, which is capable of creating a potential difference of up to 2500 volts. In this case, the leakage current is measured, and the resistance of the circuit is determined. You can’t do without it when checking the insulation of cables, electric motors, if there is a suspicion of a breakdown of their insulation. Measuring instruments with a dynamo generate high voltage which is dangerous to humans. Therefore, it is necessary to use them, using protective equipment.

Cutting tool for electrician

It is impossible to do the installation of electrical wiring without cutting tool, since in the process of work it is necessary to remove the insulation from wires and cables, cut them into pieces. Consider the popular types of cutting tools used for electrical work.

Stationery knife

For an electrician, this is an essential tool. A knife can be absolutely any kind, but a clerical knife is more often used, since it has the ability to change the blade.

With this tool, you can easily strip a cable or wire, as well as cut copper wire small section.

Side cutters

(1) A clerical knife is not suitable for cutting thick wire. To do this, use side cutters (nippers). With a certain skill, they can also strip wires from insulation.

Pliers

(2) The universal tool of any electrician is ordinary pliers. Not a single operation during electrical installation can do without them. During the acquisition and selection of pliers, one should not forget about the markings on the handles. In the presence of the inscription "1000 V", they are allowed to work without turning off the power during electrical work.

With pliers, you can easily bite off a small wire, strip the insulation, and also unscrew the nut or bolt if there is no desired key. They are used to twist the wire during connection and obtain high-quality contact.

Pliers

(3) For the convenience of working with the cable, round-nose and thin-nosed pliers are used.

The special shape of the jaws makes it possible to make installation easier and more convenient during the connection of wires to screw terminals.

Strippers

(4) If the amount of work is large, then strippers are used to speed up the process of stripping.

With one movement of the handle, the insulation is removed. Built-in wire cutters can cut the wire into specific pieces.

cable cutter

A cable of significant cross-section is cut with a special cable cutter. They may differ different options execution.

Screwdrivers and wrenches

Wires can be fixed on the device terminals different methods: spring-clamping, or screw. The spring-clamping method has appeared recently, but has already become popular.

The device of the spring-clamp terminal block is simple. A spring presses on the contact and presses it. The spring is pressed with a screwdriver, the wire is inserted, the screwdriver is removed, and the spring fixes the wire.

Types of screwdrivers

For different types of connection elements, different screwdrivers are selected.

Spanners

It is allowed to work with such keys only when the voltage is off, since they are completely metal, the handles are not insulated.

adjustable wrench

Not to carry a whole set wrenches, often take an adjustable wrench that fits almost any size.

socket wrench

Some bolts and nuts are located in places where no wrench other than a socket wrench will fit.

Tip crimping

Some electrical installation operations consist of crimping lugs on wires. Tips are used for joining wires from different metals, reliable cable connection, or thick wire. Such tips are attached by crimping. For this, apply different instruments(presses).

AT living conditions It's not often that you get a chance to get one like this. Simple tips can be crimped with pliers. Powerful tips are crimped with a hammer and chisel. The blow of the chisel must be directed to the center of the tip, pressing it inward.

Soldering tools

The most popular type of wire connection is. The wire is heated until the solder melts, and the material is coated with a flux.

In furnaces soldering of thick tires is carried out, as well as tinning of workpieces.

Autonomous lights

Electricians mostly work with the electricity off, in dark places. Therefore the most important additional tool for an electrician is a flashlight powered by batteries or batteries.

It is convenient to use flashlights that are attached with an elastic band on the head. They do not occupy hands and illuminate the place well.

Auxiliary tool for electrician

When performing electrical installation work, it is often necessary to fix sockets, switches, boxes, etc. For this, grinders, punchers, wall chasers and other devices are used.

The set of various electrician's tools can vary greatly in content. It depends on the level of complexity of his work. When choosing and purchasing constituent elements you don’t have to stop at cheap purchases, as such tools and devices will not work for long, and soon you will have to buy others again.

But buying too expensive specialized samples is also not worth it, since many of their functions may not be used by you. There is no need to buy overalls, gloves and special shoes. Shoes can be used with any rubber sole. Clothing should not contain metal parts.

The main principle of the work of an electrician is his attentiveness and caution, which do not affect the number of tools and their cost.

Today we will talk about what tools an electrician needs to repair and. It should immediately be noted that the set of fixtures and appliances will depend on many factors: the level of professionalism of the master, the intended purpose (homework related to electricity or electrical installation on the road), etc. Since our informational portal created for home craftsmen, then we will only talk about those devices, power tools and accessories that will be useful to an electrician directly in the house when working with voltages up to 1000 volts. We conditionally divide the list of tools for electrical installation into measuring instruments, hand tools and power tools, providing a description of the most important items.

Hand tools

So, first we will provide you with a set of hand tools for an electrician, so that you know what you need to buy in addition to the kit available in the house.

Your suitcase must contain the following items:

1. Screwdriver Set. When installing sockets, switches and other electrical wiring elements, you can’t do without screwdrivers. You need not only a curly and straight screwdriver, but also an indicator one, in order to be able to determine the presence of voltage on the bare terminals. Read about it in the corresponding article. We also talked about all the most popular ones separately.
   
2. Mounting knife. Without this tool, it is difficult to imagine electrical work. In your own box with various tools, you must have a knife and a set of blades. Immediately you can immediately add, which also does not hurt: a special knife for electricians or a stripper.
3. Pliers. It would be more correct to say - the pliers that the electrician-installer needs not only to bite the wire, but also to complete it.
   
4. Side cutters. While many pliers include wire cutters, it's best to buy professional side cutters with a good blade. Using this tool, you can not only bite thick wires during installation work, but also remove insulation from wires if there is no stripper at hand.
   
5. A hammer. Like any other installer, an electrician must have a hammer in his case. Using this device, you can drive a dowel into the wall, make a strobe (paired with a chisel) or hammer in a bracket (as one of the options).
   
6. Chisel. We have already said about it - if you need to manually carry out a strobe, you cannot do without a chisel. At the same time, when installing electrical wiring in wooden house Be sure to keep a chisel in your suitcase.
7. Round nose pliers. They are far from always used for electrical work in a house or apartment, but still have their own certain value - with the help of this hand tool, the home master will be able to figuratively bend the wire to connect certain types of contacts.
   
8. Crimping pliers. If you most often use sleeves, like, then in the list of necessary tool bring in the pliers too.
   

Here is the whole necessary set electrician's tools. Well, if you don't have it yet full list, then all the necessary tools can be purchased at any hardware store or order online. We've seen quite a lot positive feedback about the online store KrepezhMaster. The page https://krepegmaster.ru/catalog/instrumenty/ presents big choice tools, and here you can study their characteristics in detail and compare prices.

Please note that in the suitcase you must definitely put more electrical tape, various heat shrinks, a marker and a tape measure. You can’t do without these devices when installing electrical wiring with your own hands. We also recommend buying a special belt for the entire above list of items, on which you can attach anything: from a hammer to a screwdriver. In addition to the belt, installers wear specialized vests with many pockets, which is also convenient for storing tools for various types of electrical installation. In the photo below you can see what the belt and vest look like.

Convenient kit from ProSkit

Measuring instruments

To this category necessary items for home master can be a multimeter. It is enough to buy this measuring device so that you can measure the voltage, resistance and current strength in a 220 and 380 Volt circuit (it is unlikely that there will be more at home). Using the tester is not difficult, even for a novice electrician, we talked about this in detail in the article -.

Calipers. Oddly enough, but even in simple homework, you may need this manual one, but still measuring tool. With the help of a caliper, it is possible, which is very important in electrical work, if there is no marking on the outer insulation of the conductor.

The video provides an overview of all the most important tools that an electrician can use not only at home:

Complete electrician's bag

If we talk about measuring instruments for electricians who are engaged in electrical work, we additionally recommend purchasing a megaohmmeter. This device is needed in order to be able to check the insulation resistance of a wire or cable, which is especially important to do after wiring. You can also additionally replenish the arsenal with a hidden wiring detector, which will allow you to quickly determine exactly where the wire passes in the wall.

List of power tools

Well, and closes our list of tools for an electrician, the following set of items:

• Perforator with a set of drills and crowns (for wood, concrete). Using a puncher, you can make a round strobe for, as well as a groove for laying electrical wiring in the wall. This versatile power tool is a must-have on a shelf in your home workshop.
  
• Wall chaser. More professional tool for an electrician - a wall chaser, with which you can quickly and dust-free conduct a network of gates throughout the room. Its main disadvantage is high price, but in this case you can cheat and . homemade tool will not interfere with the set of a home electrician.
  
• Screwdriver. Another equally important power tool with which you can quickly mount various switching devices, switchboards on the wall, etc.
  
• corner Sander(UShN) or as it is also called - "Bulgarian". Can be used for electrical work

Electrical work and laying electrical networks without the proper tool is impossible, so every electrician has his own set of tools and fixtures.

And sometimes at a good specialist in electrics, the set of tools is not inferior in quantity to the tool of the same car mechanic.

Tool types

An electrician's tool can be divided into main and auxiliary.

Also, tools can still be divided by type of use: electrical - an electrician checks networks, connects wires, installs electrical appliances, and installation tools - with the help of which the electrical network is laid and installed.

An electrician does not have so many electrical tools and partings, but they should always be at hand.

Often, for this, electricians use special belts with tool pockets.

This kit includes:

• Knives;
• Screwdriver Set;
• Pliers, pliers, wire cutters, stripper;
• Measuring instruments (multimeter, current clamps);
• insulating materials.

When laying networks, as well as installation electrical equipment In addition to the specified tool, an electrician may additionally need:

• Perforator with nozzles (drills, crowns);
• Screwdriver;
• wall chaser;
• Press key;
• A hammer;
• Electrical level, tape measure;
• A set of open-end and box wrenches;
• Tools under certain conditions works.

And these are just the tools and equipment that an electrician may need, but there are also consumables.

But for now, we are only interested in tools and devices, and also what they do.

Knives

So, a good electrician has several types of knives in his belt pockets. The first is a regular folding knife. It is used for various purposes - trimming, stripping, etc.

The main one is an electrical knife, with special form blades.

In addition to the shape, its blade is sharpened on both sides, which allows stripping wiring in two directions - towards itself and away from itself.

Some types of electrical knives have a special heel at the end of the blade.

Such a knife allows you to cut the lumbar insulation of the wire without possible damage to the internal insulation of the cores.

The third type of knife that an electrician can find is a regular construction knife with interchangeable blades. It can be used just like a regular folding knife.

Screwdrivers

One of the most important tools for an electrician is a screwdriver. Each specialist has several types of screwdrivers, but they are all specialized electrical ones.

Their feature is improved protection. Usually, in such screwdrivers, the tip is covered with a non-conductive material on top, only the tip of the screwdriver is exposed.

A Phillips and flathead screwdriver is required. The best option is the presence of several screwdrivers with different sizes.

Also used by electricians indicator screwdrivers, which, in addition to the possibility of tightening and unscrewing the bolts, also allow you to check the presence of voltage in the wiring before starting work.

A simple indicator screwdriver is equipped with a diode light. When you touch the tip of a screwdriver to the wire, if there is voltage in it, the light will light up.

More complex are indicator screwdrivers with a display. In addition to determining the presence of voltage in the wires, this screwdriver also displays the voltage voltage.

Often there are sharpened blades on the jaws of the pliers for cutting the wire, but few people use them, since the quality of the cut of the cable with pliers is low, while the edge of the wire is somewhat compressed.

For cutting the wire, it is better to use wire cutters. Their blades are certain form, which allows you to make a high-quality cut without compressing the edges of the cable.

Stripper - special tool, which allows you to quickly and efficiently remove the insulation from the wires, while it does not damage the wiring cores.

Its use makes it possible to carry out installation work much faster.

Measuring instruments

Also important is the presence measuring instruments. The appearance has greatly facilitated the life of electricians.

It is enough to have only this device to make all the necessary measurements.

But you can only perform all measurements by connecting a multimeter to stripped wires, which is not always convenient.

Current clamps allow you to measure the current without the need to break the wiring for connection.

It is enough to place the wire in the clamps so that this device shows the current strength. Based on this, it turns out that an electrician needs both of these devices.

There are also combined devices, including both a multimeter and current clamps.

Insulating materials

The presence of insulating materials is mandatory. Two types of such material are used by electricians - electrical tape and heat shrink.

Both of these types allow you to isolate the connection points to exclude the possibility of a person touching bare wires under tension.

Insulating tapes are fabric (cotton, lavsan), impregnated with a special insulating adhesive or polyethylene, with an adhesive surface.

Heat shrink tubing insulating material different diameters that are from impact high temperature shrink and adhere to the joint surface.

Tool required for installation work

Let's move on to the tool that an electrician will need to lay and.

So, a puncher with drills allows you to make holes in the walls of the building for pulling wires.

The same device, but with crowns, makes recesses in the walls for installing sockets, switches, junction boxes.

A screwdriver will be needed to quickly tighten all kinds of screws during installation work, for example, to fix tunnels into which wiring will be laid. Also when working at a distance from the source industrial network convenient to use special .

With a wall chaser, small recesses are made in the walls for laying wiring in them - strobes.

Without this device, an electrician will have to make strobes either with a puncher or with an angle grinder with a diamond wheel, which is very inconvenient and time consuming.

The press wrench is used by electricians to compress special copper caps on twisted wires. The use of this key allows you to strengthen the connection of the twisted wires.

In general, for electrical work at home, you may need the most diverse.

However, without the main tool, it will be almost impossible for a specialist to perform the required work with high quality.

If you are planning to do your own wiring, installation and connection of sockets, you will need a decent amount of various instrument, you will need measuring instruments and some power tools so that the work goes faster. What electrician's tool is needed for a home master, what should it be - read on.

Hand power tool

It is convenient to keep an electrician's hand tool in a suitcase - a special plastic case with holders, a converted diplomat or a small suitcase, bags with large quantity departments, but they are not so convenient.

There are ready-made kits for an electrician, but good quality the tool is expensive, it is not always possible to lay out a fairly large amount at once. Therefore, many people prefer to collect it gradually, buying separately as needed, choosing handles, weight, even appearance. What should be in the bag? Many different things, but usually the following tools and fixtures are available.

Screwdrivers

A home electrician cannot do without screwdrivers. We need them flat and cross-shaped, and of different sizes. It could be a set of screwdrivers different sizes and shapes or one handle with interchangeable pads. But since this hand power tool, the handle must be made of dielectric material, must have a finger rest.

Also, branded screwdrivers have an insulated metal shaft, only a small piece of metal remains open. This reduces the chance of making a short circuit during operation. Such screwdrivers are not cheap, but you can insulate a regular screwdriver heat shrink tube. The effect is no better.

There are also torque wrenches. The fact is that when connecting the same machines in the shield, when connecting wires to the screwdriver terminals, when connecting household appliances, it is required to tighten the contact with a certain force. This force is usually prescribed in the instructions and is expressed in nanometers. But since this force cannot be measured with an ordinary screwdriver, they simply try to tighten the contact harder. But in order not to guess and twist at random, you need a torque screwdriver.

They are made mainly for bits, a mechanism is hidden in the handle that allows you to create exactly the specified force. It is set on a scale at the top of the handle. Then you work on it as usual, but when you apply more force than the given bit, do not spin, but slip with a characteristic sound. So it turns out that you tightened the contact with the required effort. What else needs to be said to spin under standard requirement at 2 Nm - it needs to be sooo decently strained.

open end wrenches

If you are going to deal with the electrician only in the apartment, then the keys may not be needed. But if there is a garage or a cottage, then without them there is definitely nothing.

You may need a variety of sizes, but mostly small and medium. They will be boring from 6 mm to 17-19 mm. Since this tool is usually operated with the power off, it comes uninsulated.

Pliers, pliers, wire cutters

All this electrician's tool must have insulated handles, and the insulation must withstand voltages up to 1000 V, which should be written on the handles. These devices sometimes have to work without removing the voltage, because the requirements for insulation are high. Even if you are not a professional electrician. Electric shock has the same consequences for everyone. Therefore, it is better not to save money and buy a tool with high-quality insulation.

What tools are needed? Quite a long list, but some can be dispensed with:

These are all electrician's hand tools general purpose, but there are also special ones.

Monter's knife

Remove insulation from a cable or wire - this will require an electrician's knife, which is also called a fitter's knife. It comes with a removable blade that still extends. This is an improved and more reliable variation of the wallpaper knife or paper knife.

The second option is with a folding blade. It works on the principle of a penknife, but again it has some peculiarities - the blade is wider and thicker, there can be a hook at the end, which is convenient to cut the cable insulation.

In theory, a fitter's knife should also have a handle that can withstand a voltage of at least 1000 V. But they usually work with stress relieved, so in this case the requirement can be neglected.

Stripper - stripping tool

When installing electrical wiring, connecting household appliances, it is necessary to remove the insulation. If you have a certain skill, you can get by with side cutters or wire cutters, but by the time you learn how to do this, you will exhaust a lot of wires. In addition, even with solid experience with thin or stranded conductors, it is difficult to work with side cutters - the cores are often damaged. Therefore, it is advisable to have an electrician's suitcase with a stripping tool or a stripper.

They come in a variety of configurations that have a slightly different mechanism of operation, but they quickly remove the insulation and leave the wire intact.

Chisel and hammer

What else you can’t do without when laying wiring is without a chisel and a hammer. After all, the wiring is laid mostly covertly, and for this you need to do it. If the amount of work is small, you can handle it and hand tool- a chisel with a hammer, but it is better to have at least a puncher on hand.

Measuring instruments

For any trouble with household appliances or wiring problems need to be measured. To do this, your electrician's suitcase must contain a multimeter. For simple definition the presence of a phase will require an indicator screwdriver, and in order to calculate the cross section of the conductor, you will need a caliper or micrometer. These are all the necessary measuring instruments that a home electrician should have in their toolbox.

Measuring instruments should be in the bag with power tools

Multimeter or tester

There are two types of household electrical measuring instruments - testers and multimeters. In testers, the measurement results must be calculated on the appropriate scale and arrow deviation, taking into account the divisor / multiplier that is set at the time of measurement on the switch. In general, one must be careful and consider that it is not always easy. Therefore, probably, multimeters are more common in an electrician's suitcase, which immediately give the result on a digital display, and even with units of measurement.

Multimeters are more popular - it is easier to take readings with them

What is important to pay attention to when choosing a multimeter is the accuracy class and measurement limits. The higher the accuracy class, the lower the error of the device. So multimeters with an accuracy class of 2.5 give an error of 10%. Even if you need to measure the voltage in the 220 V power supply, plus or minus 22 V is a lot. If we talk about more accurate measurements, such deviations are generally unacceptable. Therefore, multimeters with an accuracy class of 3.5 are most widely used, which give an error of about 1%. It's already over reliable results, which is enough for a home master. There are devices with class 5 and above, but their cost is high and for domestic needs it is not so important.

Read how to take measurements with a multimeter.

Indicator screwdriver

The second necessary tool is an indicator screwdriver. This is a small device that costs very little, but which is very convenient to use. The presence of phase voltage on the conductor is checked by simply touching the tip of a screwdriver to the bare conductor, live part or socket. The LED built into the handle lights up.

This is really a very necessary tool for an electrician, with which you can instantly test the presence of a dangerous phase voltage before starting work.

Vernier caliper or micrometer

Oddly enough, but a home electrician should also have this tool. It will come in handy when buying a cable or wire. The thing is that the actual cross section of the conductors differs significantly from the parameters declared by the manufacturer. And since the load with which it can work depends on the cross section of the wire, such a difference can be critical and lead to wiring failure and even to a fire.

Therefore, before buying any cable or wiring, it is worth measuring the diameter of the wire, determining its cross section. And based on this data, make a decision on whether to purchase this product. About,

power tool

The presence of this group of tools is not at all mandatory, but it significantly speeds up the most unpleasant job- strobe device. A variety of tools with saw blades are suitable for this, but two are traditionally used: a hammer drill with a blade attachment and a wall chaser. A puncher, in general, is a useful and relatively inexpensive thing, because many people have it. With its help, you can relatively quickly make grooves in the walls for laying wires - strobes.

Hammer drill - from the category of tools that make life easier for an electrician

There is another device that can quickly solve the problem of cutting holes for installing sockets and switches - this is a “crown” attachment for the same hammer drill or drill.

Professionals have a wall chaser in their arsenal. This is a specialized tool with two parallel saw blades that are set to the desired distance, setting the width and depth of the strobe. These devices connect to industrial vacuum cleaner, so that when working, dust flies at a minimum. But the price tag for this equipment is high and hardly anyone will buy expensive highly specialized equipment just for home use.

This is, perhaps, all the necessary tool for an electrician for home use. No, many more tools will be useful - a screwdriver to tighten the contacts faster, a stapler to quickly fix the wires, etc. But we have named the main list.

The article discusses the minimum necessary tool required for electrical work in electrical networks with voltages up to 1000 V, including when working with home electrical wiring.

The set of tools that you may need to repair or install the electrical network can vary greatly. But at the same time there is a tool without which it is impossible to do. It is he, along with insulating tape, heat shrink tubing and small wires, that is always at hand for any electrician:

1. Control and measuring device (multimeter and probe).
2. Pliers.
3. Adjustable wrench or set socket wrenches.
4. Crosshead screwdriver.
5. Straight strong screwdriver.
6. Straight thin screwdriver.
7. Torch.

With the growth of professionalism, an amateur electrician may have an additional tool to simplify or speed up the work. Consider the possible "arsenal" of an electrician in more detail.

Tool for monitoring the state of the electrical circuit

The first thing an electrician must do is to protect himself from electric shock, so he not only disconnects circuit breaker or another device used to de-energize part of the mains, but also controls the absence of electricity using a special device.

Phase absence-presence probe in the network 220 V, 50 Hz

The minimum necessary, and at the same time a very cheap tool is the so-called control, or probe. With it, you can find the "phase", which is necessary for correct connection a number of electrical appliances.

Most probes are made in the form of a screwdriver, but you should not use them for installation work, as they are made of fragile metal and plastic. During installation, the body of the probe often breaks, and the metal nose bends and crumbles.

Universal multimeter

The most informative device, which allows not only to check the presence or absence of voltage, but also to diagnose a malfunction, check the correct installation, is a multimeter, which many people call “tseshka”, since one of the first massively sold devices of this type was called that.

There are a large number of devices of this type on sale, but since they often fail (for example, when trying to measure resistance on a non-de-energized network element), there is no need for beginners to purchase expensive, professional devices.

When choosing a device, you should pay attention to the quality of the probes sold in the kit. The probes should be soft, elastic, easy to withstand bending in any place. The second thing you should pay attention to is the quality of the case; ideally, a special rubber case should be put on it. The device should allow measuring DC and AC voltage and resistance, other options are rarely used.

Specialized multimeter

Professional electricians may be interested in specialized multimeters.

So, the model shown in the photo allows you to determine the inductance, capacitance and resistance of the measured circuit with great accuracy.

Current clamp

No less popular are current clamps that allow you to measure the current flowing through the wires without direct contact with conductive parts, connect without breaking the circuit.

This device is universal, it allows you to measure current, and with the help of additional probes - direct and alternating voltage, circuit resistance.

Megohmmeter

A very convenient device that allows you to check the quality of insulation electrical circuit, is a megger.

This device, using the built-in dynamo, can create a potential of 500, 1000 or 2500 V and, by measuring the leakage current, show the resistance of the circuit. It is indispensable for testing electrical cables and motors when insulation problems are suspected.

Cutting tool

Working with electrical wiring provides for the need to remove insulation, cut to length electric cable or wires, so you can’t do without a cutting tool during installation work.

Stationery knife

The main tool of any electrician is a knife. You can use absolutely anything sharp knife, but the most convenient are stationery knives with a replaceable blade.

With such a knife it is convenient to strip wires and even cut thin copper wire.

Nippers (side cutters)

In order to cut thicker wires, and with some skill to strip them, various wire cutters or side cutters are used.

cable cutter

A thick cable or its individual cores are cut using cable cutters of various designs.

Classic shape pliers

For an electrician, there is no more versatile tool than pliers. When buying them, you need to pay attention to the inscriptions on the plastic part of the handles. If there is an inscription 1000 V, then they can be used to perform electrical work, even without turning off the voltage.

Pliers make it easy to cut through a thin cable or wire, they can be used to remove insulation from wires. In the absence of the required open-end or box wrench, pliers can be untwisted or pulled bolted connection. Pliers can be used when making a twist-type connection of wires, providing better contact. Pliers are the most universal tool electrician, you should not save on its quality.

Pliers

Specially shaped pliers such as round nose pliers and thin nose pliers can be used to optimize cable handling.

The rounded and thinned shape of the jaws of this type of pliers makes it possible to simplify the installation of monolithic wires to screw terminals (making a “ringlet”). The main thing in them is durable metal and high-quality plastic on the handles.

Strippers

If necessary, perform a large number installation, a specialized tool designed to strip wires can significantly speed up the work different diameter called a stripper.

Stripping wires with a stripper is done with a single push of the handle, which significantly reduces the time required for stripping wires. With the help of built-in wire cutters, the wire is cut to specific lengths.

Screwdrivers, wrenches, hexagons

Wiring of wires can be carried out using several types of wire fixation: screw and spring-clamp.

If the first type has been known to everyone for a long time to one degree or another, then the spring-clamp type has appeared relatively recently, and, due to the ease of installation and the reliability of fixing the wires, it is actively gaining popularity.

Mounting the wire in a spring-clamp terminal block

The principle of the spring-loaded terminal block is simple. Inside there is a conductive plate, on which the spring presses, with the help of a screwdriver the spring is pulled back and a wire is inserted into the space formed between the spring and the conductor. After the screwdriver is removed, the spring securely fixes the wire.

The main types of screwdrivers required for electrical work

Based on the need to twist or press different kinds connecting elements, an electrician selects the optimal set of screwdrivers, wrenches or socket wrenches, hexagons.

Wrenches (open-end and box)

An electrician's kit should include both Phillips (+) and straight (-) screwdrivers of various sizes. When choosing, it is advisable to give preference to those screwdrivers on the handle of which there is a mark of 1000 V. Good insulation is necessary, since quite often it is necessary to “tighten” various screw connections without relieving stress. The tip of such screwdrivers is covered with plastic to minimize the likelihood of accidental contact with other current-carrying parts of the electrical installation.

Since wrenches and open-end wrenches are made entirely of metal, make sure that there is no life-threatening voltage before using them.

adjustable wrench

In electrical installations, bolts and nuts of various diameters are used, because of this, it is necessary to have a solid supply of wrenches with you, so many electricians prefer to get by with pliers and an adjustable wrench.

socket wrench

In many seats, the nuts and bolt heads are "recessed", and they can only be twisted with the help of socket wrenches.

Torque wrench with socket set

Since copper and aluminum are rather soft metals, the tightening torque of bolts and nuts in electrical installations can be clearly specified. For installation work, a torque wrench can be used, which allows you to control the applied to threaded connection an effort.

Hex key set

Many imported electrical installations and modern domestic ones are equipped with hex bolts. To work with them, you need a special set.

Tip pressing tool

A number of electrical work includes the need to put on and fix special lugs on a cable or wire.

Lugs can be used to securely connect the copper and aluminum parts of the conductive elements. They are needed for convenient and reliable connection. flexible cable or large wires. All types of these tips are fixed by crimping. For these works, various presses are used.

Press for crimping stranded wires with a cross section from 0.5 to 6 mm 2

At home, it is not always possible to take or buy the necessary crimping tool. Straight ferrules for thin stranded wire can be crimped using heavy-duty pliers that squeeze the wire and ferrule until a flat surface is obtained. Heavy-duty screw terminals can be crimped using a rounded chisel and a hammer. The blow with a chisel should fall exactly in the middle of the tip, but not cut it, but press it inward, providing compression of the wires inside.

soldering tool

One of the common types of connection of copper conductors is their soldering using tin solders. For these purposes, the wire is heated to the melting temperature of tin, and with the help of special fluxes, a tin coating is applied to it.

Soldering can be done with electric soldering irons various power, in crucible furnaces, using blowtorch kerosene lamps and even special soldering stations. The choice of soldering tool is made taking into account the size of the parts to be soldered and the required accuracy. For most household needs, a 60W soldering iron is sufficient.

Fine soldering is carried out using soldering irons with a power of 25 W, for particularly precise and complex work soldering stations are used.

By using crucible furnaces and blowtorches soldering of thick copper bars and tinning (plating thin layer tin) blanks.

Autonomous light sources

Since most electrical and repair work performed after a power failure, one of the important auxiliary tools the electrician becomes a flashlight powered by batteries or rechargeable batteries.

During installation work, it is most convenient to use LED headlamps, as they effectively illuminate the work area and do not occupy the installer's hands.

Additional power tool

Electrical work is often associated with the need to install and fasten various boxes, sockets, switches. An electrician may need to do concealed wiring along existing even walls, etc.

For these purposes are used electric drills, perforators, grinders and wall chasers. A set of necessary tools is formed depending on the task.

The composition of an electrician's kit varies greatly depending on the complexity of the work. When purchasing all its main components, you should not save on quality, because there is a lot of work ahead. But to the purchase of a specialized tool or different sets you need to approach carefully and carefully, because their cost is high, and the need for use may be minimal. Do not immediately spend money on special shoes, overalls and dielectric gloves. Gloves can be easily pierced and get an electric shock, any shoes will do, as long as the sole is rubber and without nails. Clothing should also not contain a lot of metal. The main thing in the work of an electrician is caution and attentiveness, and this does not affect the cost and quantity of the tool.
