When working in electrical installations, it is impossible to do without the use of electrical tools. The right tool is the key to quality work, as well as your safety.

I bring to your attention a description of the most common tools for an electrician and a home master, as well as what you need to pay attention to when choosing an electrical tool.

In addition to the specified electrical tool, for an electrician and a home master, you still need to have a lot of little things with you in order to perform elementary repair and installation work.

Phase voltage indicator it is used to check the presence of a phase voltage within 150-250 volts, by touching the working part of the indicator (screwdriver) to an electrical installation under voltage, and on the other hand, through a current-limiting resistance, a human hand

Before checking the absence of voltage, make sure the indicator is working by checking the voltage on a known connected electrical equipment

When choosing a tool, you need to make sure of its integrity and the presence of current-limiting resistance.

It happens that a graphite rod is installed instead of resistance, it is not recommended to trust its readings, often erroneous readings of disconnected electrical equipment, the measurement limit is from 100 to 500 volts

Sometimes sellers offer to buy an indicator containing miniature batteries and an LED, the glow of which occurs even with the touch of hands, it is strictly forbidden to use such an indicator to check the absence of voltage, such indicators are used to "ring" wires

Side cutters or side cutters it is used directly in the installation of electrical wiring when connecting cable and wire products, they allow you to work in electrical installations under voltage during dismantling.

When buying, pay attention to: the integrity of the insulation of the handles, the sign of 1000 volts, the presence of persistent protrusions for convenience and safety, the accuracy of the connection of the cutting parts in the closed state, the absence of play in the swivel joint.

Use side cutters only for cutting copper and aluminum wires; use with other metals may lead to blunting of the tool.

Pliers used directly in the installation of electrical wiring when connecting cable and wire products, allow you to work in electrical installations under voltage, for example, remove the fuse.

When buying, pay attention to: the integrity of the insulation of the handles, the sign of 1000 volts, the presence of persistent protrusions for convenience and safety, the accuracy of the connection of the cutting parts in the closed state, the absence of play in the swivel joint.

Use pliers only for cutting copper and aluminum wires, use with other metals can lead to blunting of the tool.

Electrical screwdrivers used in the assembly of electrical equipment and when connecting cable and wire products by means of bolt clamps.

When buying, pay attention to: the integrity of the insulation of the handles, the sign of 1000 volts, the presence of persistent protrusions for convenience and safety, the working part should protrude from under the insulation no more than 10 mm.

Control lamp used in the repair of electrical equipment.

The control lamp must be assembled by yourself, using a conventional E-14 cartridge (carbolite), a flexible wire 160 cm long with a cross section of up to 1,5 mm2, two cases of fountain pens (collapsible on both sides), you will also need a monolithic wire with a cross section of 2,5 mm2 and a roll of electrical tape.

When assembling, you will need an electric soldering iron, a cutter and an awl.

We pierce the back caps in fountain pens and insert the ends of the flexible wire into them, previously tinned with a soldering iron.

We solder a stripped monolithic wire to the tinned ends, longer than the body of a fountain pen, and assemble the cases.

Fold the flexible wire in half and cut it.

We connect the cut ends to the E-14 cartridge (for reasons of saving space in the bag).

Wrap the ends with fountain pens well with electrical tape.

Cutter or knife used for cutting cable and wire products.

When cutting and stripping cables and wires, take extra care not to extend the knife blade too much, the movements should be directed away from you.

Pilot lamp or lamp it is very convenient when checking the socket group for operability, it is also used to illuminate the place of work.

The control lamp - the lamp must be made by yourself, from an E-27 (carbolite) cartridge and a non-separable electric plug with a piece of outgoing cable, at least 5 cm long (conveniently suitable for office equipment power cords).

We remove the sheath from the section of the supply wire to the sealing base of the electrical plug.

We disassemble the electric cartridge E-27 into its component parts.

The base of the cartridge has a threaded hole, we screw it onto the electric plug, if necessary, cut it around the circumference to reduce the diameter of the seal.

We clean the supply ends of the wires of the electric plug, the grounding conductor can be cut off.

We charge the cartridge E - 27, connect the supply wires to the contacts of the cartridge and assemble its components.

Electronic measuring clamps used for testing and repairing electrical equipment.

When buying, pay attention to the number of measured parameters, their limits and accuracy.

The most necessary parameters: measurement of current load, up to 1000 Amperes; voltage, alternating current up to 750 volts, direct current up to 1000 volts; resistance, from 0 to 20 kOhm.

Measurement accuracy, the error of the minimum value of the indication is allowed, for example, when measuring resistance with an accuracy of tenths, an error of one tenth (0,1) is allowed

Electric soldering iron 100 watts, solder, rosin used to repair electrical equipment.

During operation, the power wire at the base of the handle often breaks off, the repair is difficult, for this, after buying a soldering iron, bend the power wire to the handle and screw it with electrical tape to make something like a loop.

In the event of a break in the supply wires, you will have a supply of wires for repairs, there is no need to disassemble the soldering iron handle.

Two-point extension, 5 m long an indispensable thing when working with electric tools.

Electric tool, perforator This is your indispensable assistant in the installation and repair of electrical equipment.

There are many different companies for the production of electric tools, the main thing is to follow the mode of operation, then the tool will last a long time.

Hammer with wooden handle necessary in the installation and repair of electrical equipment.

The use of a hammer with a wooden handle sometimes makes it possible to work under voltage, for example, gently inserting fuse-links or disconnector blades in a switchgear.

Random news from the Archive Definition of transparent objects 25.03.2022 Robots and other automated systems have always had difficulty visually determining the three-dimensional shape of transparent objects, such as those made of glass. The new system solves this problem by using a laser to rapidly heat the desired surface. The Glass360Dgree system, developed by the German Fraunhofer Institute for Applied Optics and Precision Engineering, includes an infrared laser as well as two highly sensitive thermal cameras. Within fractions of a second, the laser moves over the entire surface of the object, slightly heating it. There is no risk that the object will melt or burn, as it only heats up by 3 °C. Although the absorbed thermal energy is stored in glass or other material for only a short time, this is enough for two cameras to simultaneously record changes in the thermal characteristic of the object from two angles. This data is analyzed by a computer system, which can then determine the three-dimensional shape and size of the object. Along with transparent materials, the technology can be used to image hard-to-scan materials such as highly reflective materials or solid blacks.
