Before starting to repair an apartment with your own hands, you should think about the state of the electrical wiring. If you are inclined to believe that its replacement is necessary, start by asking about the choice of wire. As a rule, in old apartments, an aluminum wire was used, with all its advantages it is fragile and prone to microcracks. For an apartment and a house, copper wires should be preferred.
It is worth starting directly replacing electrical wiring in the house by determining the estimated load. Add up the power of all electrical appliances and do not forget about those that you are just planning to purchase. Knowing the consumption figure, it is easier to choose the wire cross-section. A wire with a cross section of 1 mm is suitable for a power of 2kW if it is copper and 1kW if it is aluminum. It is better to calculate the estimated power for each room, for some of them it is better to lay the power lines separately, given their maximum load.
To lay the wires, the walls will have to be "grooved" with a puncher or cuts with a hand-held circular saw.
But before embarking on such a responsible "event" do not forget the basic rules:
- Replacement of electrical wiring during repairs must be done completely and efficiently.
- Decide on the number and location of all appliances, sockets and switches in order to draw up a competent project with an estimated power consumption.
- Choose the material for the work, you should not save here. If this is a cable, then VVGng3 * 2.5 or VVGng3 * 1.5, if the wires are copper, if the sockets and switches are with a ceramic or other heat-resistant base and nickel-plated or chrome-plated contacts. Each separate line must have its own machine in the electrical panel.
- The connection of the wires must be done correctly, and the junction boxes must be in easily accessible places. It is always necessary to provide for backup boxes, machines, sockets.
- Working with electricity requires safety and qualifications. Therefore, if you do not own either one or the other, entrust your safety to a specialist.
Changes to apartment electrical wiring imply the compulsory drawing up and approval of the project, and implementation only by qualified specialists who have permission to do so.

Do-it-yourself electrical wiring in an apartment It is believed that, on average, a modern apartment consumes about 8 kilowatts of power. So a 40 amp circuit breaker should be used. This is enough to protect against overload and short-circuit current. Residual current devices (the so-called RCD) are needed to protect people from electrical injuries, as well as during power surges. Most often, 2 RCDs are installed, one with a leakage current of 10 milliamps (for a bathroom) and the second
