What tool do you need to work with an electrician at home?

For maintenance and installation of an electrician at home, you do not have to involve outside specialists – you have every right to do it yourself. All that is needed for this is knowledge within the framework of secondary school, experience with the instrument and, accordingly, the instrument itself. About what tool and why you need it when working with an electrician in your house or apartment – in this article.

Laying of electrical wiring
The first thing to do during the renovation is to distribute the wiring to rooms. For brick or concrete walls of apartments and houses, the generally accepted standard is hidden wiring in strips – grooves for wiring communications. In accordance with the wiring diagram, it is necessary to carry out penalties on all walls from the entrance to the apartment to the proposed installation locations for junction boxes, sockets, switches and other wiring accessories.

Keep in mind that the installation of strips in floor slabs is not allowed – to connect luminaires on the ceiling, you must either use the existing wiring (laid by the builders in the voids of the floor during construction), or lay the wiring open and cover it with a stretch or suspended ceiling.Most often, punchers are used to lay the punches – their performance is enough to carry out all the necessary work in an apartment or a small house in a couple of days.

But keep in mind that only rotary hammers that have a separate chiseling mode without rotating the drill are suitable for laying a drill . In this case, a special drill is used – a channel or groove chisel .However, it is not always possible to lay the punches with a perforator. In gypsum concrete walls, the drill can chip off large chunks, which will require increased costs for sealing the pipe after laying the wires. The same problems arise if the wall is already finished – when working with a punch, large pieces of plaster can break off, which will require re-finishing the wall. In these cases, the walls of the slab should be cut with a disc on the concrete for a dry cut, and only after that the slab itself should be laid with a flat drill.

But the grinder is difficult to maintain the distance between the cuts and their depth. If indent is necessary to cut through much better use wall chaser . It has two discs fixed on the axis at once and there is an emphasis to maintain the depth of immersion of the discs into the wall. With this tool, the lines are laid quickly, look neat and require a minimum of effort for the subsequent termination.

If the pipes are laid in a wall with valid wiring, before starting work, you should make sure that the future pipe does not cross the existing wires anywhere. For this, wiring detectors are used . Live wire and magnetic metals in the wall will be able to find even the simplest models . More sophisticated devices are able to search for non-conductive objects in the walls – wooden beams, plastic pipes, and even just voids.

Of course, a hole for installing a socket box can be hollowed out with a puncher using a conventional drill, but this is not the best option – it is long and inconvenient. It is best to make holes with crowns – 68 mm for socket boxes and 75-125 mm for mounting boxes of the appropriate size.

Also at this stage you will need a screwdriver – in order to fix the socket outlets in the hollowed-out holes. However, this can be done with a screwdriver.

After preparing the walls and installing the socket boxes, you will need to lay cables and connect them in accordance with the diagram. In this case, the ends of the cables must be cut – remove the outer insulation and bare small (5-10 mm) sections at the ends of the wires. If there are few connections, this can be done with a knife . But what if there are dozens or even hundreds of them? In this case, time, nerves and fingers will be saved by a special tool for stripping insulation – a stripper .

Strippers are of several types. Simple models in the form of pliers with external insulation will not cope, but they will help to quickly expose a separate core. You just need to insert the wire into the hole of the appropriate size, squeeze the pliers and turn them a couple of times.

After preparing all the wiring, you can connect the entire circuit to the input machine.

All connections must only be made on de-energized equipment!

Make sure the cable clamp is not energized before using a screwdriver. How to do it? The easiest way is to use an indicator screwdriver (probe) .

The simplest indicator screwdrivers will allow you to distinguish the wire on which there is voltage (phase), from zero or not connected.

More complex models can also distinguish between a wire connected to zero of the power grid (zero) from an unconnected one.

More functional instruments are multimeters . The multimeter allows you to accurately find out the voltage in the network, determine a short circuit in an electrical device, check a battery or accumulator, measure the current flowing through the wire.

The current clamp allows you to measure the current in the wire without breaking the circuit, which is convenient for diagnostics.

At all stages of electrical installation, you will also need a hand tool – screwdrivers , pliers , side cutters . Please note that they all have a dielectric coating – this will protect you from electric shock if the wire with which you are working turns out to be energized. Dielectric coated tools have a maximum allowable operating voltage on the handle, check it. For work with household electrical wiring, a tool with the designation “1000V” is used (permissible at voltages up to 1000 V).

Screwdrivers for work with electricians must have a tip insulated along the length – this avoids a short circuit when working with a group of wires.

large slotted (SL) 5 … 6×1 and cross (PH3) – for wiring in automatic machines, RCDs and wiring accessories.
Medium slotted and Phillips (PH2) screwdrivers are used less often, but they can also come in handy when installing wiring accessories.

In order not to select all hand tools separately, you can take a ready-made set of hand tools . There are dedicated electrician kits that contain all the hand tools you need in a handy case or bag.
