Today, almost every apartment has a lot of electrical appliances. Their total capacity exceeds the capabilities of the internal network, which is also designed for Soviet energy consumption standards. A new electrical wiring in the apartment can be completed entirely on its own without the involvement of specialists. Representatives of the supplying organization will be needed only at the final stage.
They carry out the connection of intra-apartment wiring and sealing metering devices. A single-phase wiring diagram in an apartment is performed without grounding. Be sure to install short circuit protection devices. Two conductors are laid to each consumer: the first is a phase, the second is zero. The wiring is carried out in a hidden manner in the grooves-strobes.
Preparation: organizational and technical part
For the work will require electrical materials and tools. First of all, you need a wire of the PVS or ShVVP brand with a copper multicore conductive part and double insulation. The section is selected in accordance with the load. As a rule, for outlets it is at least 2.5 square meters. mm and for lighting devices - 1.5 square meters. mm The electrical wiring in the apartment is usually combined with the repair.
The technical part of the preparation for the reconstruction of the network consists in the removal of furniture and other items from all rooms. The walls and ceiling are marked with gates, which are most conveniently cut using an angle grinder with a diamond wheel. Before starting work, the old wiring must be de-energized. It is best to buy everything you need in a construction supermarket, where prices are slightly lower.
Basic operations
By pre-marked channels we make the gating of the surfaces of walls and ceilings. It is performed as follows: “grinder” we make two parallel incisions to a depth. Then, using a puncher, we make a selection, in the places of installation of junction boxes we expand the chute to the required size. We perform all work with glasses and a respirator, this will avoid damage to the organs of vision and breathing.
At the next stage, we lay out the wires according to the wiring diagram and fix them in the strobes. This is not difficult if you use special plastic holders. Their cost is low, but the speed of work increases significantly. The general direction of the process is the wiring of the electrical wiring in the apartment: from the installation site of the meter to electrical appliances and sockets.
Electric installation work
This is the connection of individual conductors to a working circuit. At the locations of junction boxes, switches, sockets, lighting fixtures, wires are stripped from the insulator. This can be done with an ordinary knife, but it is more convenient to use a special tool. The electrical wiring in the apartment is done so that the switch breaks the phase, and the base on the outer ring has zero.
Following this rule will help avoid electrical injuries in the future. Everyone who read this article got a good idea about how to properly make the wiring in the premises. However, checking and connecting the internal network is still better to entrust to professionals.
