Replacement of electrical wiring in the apartment during overhaul

Overhaul in an apartment is a natural disaster that is familiar to many of our fellow citizens. What is included in the mandatory program of this event?

Removing furniture with partial rejection, removing the old floor covering and, possibly, the floor itself, peeling old wallpaper, dismantling old plumbing, interior doors ... And this is just the beginning. Next on the schedule is the replacement of the risers of heating, domestic hot water, cold water and sewage, work to align the walls, floor and ceiling, replacing doors and windows, installing new coatings for the same walls, floor and ceiling.

In general, plenty of work. And the older the apartment, the more problems you will have to face. But we did not mention one important point, which is most rational to coincide with the general overhaul of the apartment. It is about replacing the old worn electrical wiring.

But replacement of electrical wiring in the apartment during overhaul necessarily recommended for execution, especially if this same wiring has not been repaired since the house was built, and the house was built in the Soviet era. The need is dictated, for example, by the fact that at that time the preference was given to the simplest grounding system - TN-C. The TN-C system is characterized by the presence in the household network of only two conductors: the working phase and the working zero. A protective neutral conductor is not provided in this system, and this is contrary to modern electrical safety standards.

Of course, changing the grounding system in a single apartment is an almost impossible task. In his apartment network we can only lay an additional third wire without connecting it in the apartment panel until the common house engineering networks are brought into line with the current requirements of regulatory documents. But it still has to be done sometime. And overhaul is the most suitable moment for this.

In addition to the absence of a third wire in the line, the old wiring is minimalistic, both in terms of the cross-section of the conductors, and in terms of the number of outlets for each room. So in the panel "Khrushchev" ordinary phenomenon, you can recognize only one single socket for the entire kitchen, not counting the one that designed to connect the stove. At the same time, entering a wire with a cross-section of 2.5 squares is also not uncommon for old apartments. Moreover, copper in those ancient times was not yet used, and we are talking exclusively about aluminum.

And, in general, it must be recognized that for the level of electricity consumption of that time all this was more than enough. After all, even an electric kettle was then far from every apartment. And the power of the latter, even in the case of its presence, was not comparable with the power of modern quick-boiling specimens.

However, today in every apartment there are so many powerful household electrical appliances that the need to reconstruct old wiring and get rid of most extension cords and tees ripens with all the evidence.

And since during the overhaul in the apartment a fair amount of noise, dirt and garbage is supposed to be, it is at the preliminary stage, before engaging in interior decoration, you should think about replacing the wiring.

Of course, at the same time, the installation of cables is possible in the boxes, but with a major overhaul, it’s a sin not to take the opportunity to make a neat and consistent with all safety requirements covert wiring. Moreover, in this situation this will be the least time-consuming option. And this, of course, will reduce the total cost of replacing wiring.

So, the most preferred option for replacing electrical wiring during overhaul is a hidden installation in the gate, under a layer of plaster, under the skin, in structures made of sheet materials, in the screed or just under the floorboards.

In the case of laying the cable in the gates, you can not use any pipes, but install the lines “as is” using plastic dowel clamps. At the same time, however, the formal requirement for wiring interchangeability is violated, but this requirement can actually be neglected in favor of labor productivity and lower cost of work.

The most effective, but also the most dusty strobing method at the same time - with the help of a grinder with a diamond disk. Holes for installing sockets and junction boxes perforator with a crown for concrete. There is nothing to do with the usual percussion drills here. We must not forget about the means of protection: a grinder is needed for a grinder, and a worker needs a respirator to protect his respiratory organs. Safety glasses will not be superfluous.

Those who have ever produced replacement of wiring in a panel house, Certainly were able to appreciate the fact that the concrete of the building panels is ditched very hard. But there is one pleasant moment: in the manufacture of these same panels, ready-made grooves and holes for engineering communications were provided. Of course, they are not always located exactly where necessary, but still they must be borne in mind. Moreover, bearing walls and ceilings cannot be gated out categorically.

The option of installing cables on the floor or in building structures is considered when it is simply impossible in a different way. For example, when the apartment is in a wooden house.

It also often happens that some part of the wiring may be hidden in drywall constructions. This is possible, for example, when installing recessed spotlights. Then the wiring is carried out in pipes (in case the wall material is non-combustible, then the pipe can be made of PVC, including corrugated). Pipes are attached to the surfaces of walls or ceilings using brackets or clips.

Finally, we list the main advantages of replacing wiring in a panel, wooden or any other house during the overhaul:

1. You can bring the wiring in maximum compliance with modern safety requirements,

2. You will be able to make all the wiring in the apartment exactly "for yourself." Each socket, lamp, switch and even a panel of apartments will be located exactly where it will be convenient and safe for you. The number of outlets and fixtures will also meet your needs - no tees or extension cords will be needed.

3. And the main thing is that all this will cost you "little blood." After all, you still have to peel off the wallpaper during a major overhaul. You will also be forced to leave your home during the repair. Dirt, noise and other repair troubles are also inevitable. So why not at the same time complete the wiring replacement, taking advantage of this situation and saving on many costs.
