Replacing the wiring

Replace the wiring need to do about eight out of ten cases. This is due first of all   that is the wiring, which sit at home now and especially one that is already older than 10-15 years, meets state standards for a long time accepted and adapted to transmit power required modern electrical appliances (the number of which is growing steadily).  

The second factor – This connection wires tightly immured in the wall (this must not be allowed, but, nevertheless, is very common). You can never certainly determine their reliability. Problems of the   it is most likely to occur in the joints and bends the wire, which is particularly important for aluminum wires, as a rule, used in the « native » wiring. And if a problem arises, in order to eliminate it, you have to batter the wall, and do so much of overhead after finishing work.

A little bit about how to do it

The first method -to walls are cut or hollowed out grooves (Grooves), in which subsequently recessed wiring. They do a wall chaser, or punch with a special nozzle. You can also use the « grinders », but I think this option is less convenient and less justified. What to prefer in each case – It is solved in place and does not affect performance. By the time the work takes two to three days, the noise and dust will be a lot. Watered cutting grooves for dust control do not advise, because It needs a lot of water and can easily leak to the neighbors below. You can also use a vacuum cleaner, but in any case it implies the existence of an assistant, which leads to a rise in the cost of the work. And in any case, the noise level will not be affected.

Further Grooves laid wiring and there are several possible options. The best way to lay wire in a metal tube and in this form walling them in cutting grooves. This will avoid accidentally drilling wiring or any mechanical damage. A significant drawback of this – relatively expensive material.


The second method – this packaging in special wiring corrugated hose, but will protect it from damage by the drill and so on, but can be protected from moisture. A special need for such protection, but if the budget allows, it is better not to neglect. You can put the wiring in the cutting grooves without any packaging, but the presence of the compounds do not advise this. In connection wire bush is better avoided, and if this is not possible, bring them together with wires lighting installation boxes of switches, where their condition can be checked at any time by   easily.

immurement wires in the cutting grooves without additional protection has a positive side – On the one hand it saves on the material, on the other hand it turns out good heat sink that has a value with an increase in power. There are other ways « hide » wiring (in the existing slot under the screed, etc.), but to me they are less reliable.  


As replace wiring in general, it is convenient more and what you need for you to choose the number of outlets and switches, as well as their location in the apartment. In the end, and repair You ought to for the sake of comfort and convenience.


Many people prefer to hide in the walls and low-voltage cables ( TV , telephone, Internet, etc. .), but in this case, to avoid the appearance of interference, & nbsp ; I would advise you not to use (at least for long stretches) Grooves with some wiring, but make them individual. Although it seems more appropriate to hide « low current » under the plinth.


And finally, what it costs. The average cost of the work in Moscow for the complete replacement of electrical wiring in a studio apartment (off the old wiring, cutting grooves for new wiring, connections, installation of sockets and machines, embedding cutting grooves and garbage) is about $ 1,000. Plus $ 150 for each additional room. But the final price is negotiated on the spot and can vary in either storonu.Tak that replace the wiring in the apartment with his own hands - it is profitable.
