As a man without blood is simply lifeless body, and the apartment without electricity today remains the only unsettled box.After all, thanks to electricity, we get a lot of benefits, without which we can not imagine their lives.However, the state of power supply in our house, we must also keep in good faith, as well as their health.And do not wait for the moment when replacing wiring in the apartment becomes the resuscitation process.It is best to change the wiring even before a fire occurs by a short circuit in the worn joints.

almost always people with Slavicmentality become involved in long and dreary affair only at the moment when the "roasted rooster peck" in neudoboskazuemoe place.Is this situation to the replacement of electrical wiring?More often.Here are the main reasons for which people decide on such a feat:

  • overhaul the apartment or remodeling (which also ends with a big repair)
  • problems with electricity - frequent power surges, sparking outlets and switches Finally, nearly occurred (or did happen) fire because shutting wiring
  • increase in the number of electrical appliances, and increased as a result of the load on the electricity supply system

In fact, it is the third reason has to be paramount.But, alas, not all of us are so cautious.But how many problems could be avoided with the timely replacement of electricians.

But if we got down to business, you should do it properly.First and foremost, we just have to calculate what capacity and in what areas will be in our new wiring.What exactly needs to be done:

  • for devices with maximum power consumption (mostly fall into this category: electric stove, water heater, washing machine, refrigerator, and the like) it is best to schedule a separate line wire, designed for increased load
  • advance look after the place for sockets and switches, so they were really easy to use
  • determine the type of fixtures throughout the apartment
  • calculate the total power consumption for all instruments and equipment that you have (this can be done on the data sheets) and morebetter take into account the planned acquisition

That is, we need a wiring diagram.If you are into electricity, then we can do it ourselves, but in any case consult a specialist will not be superfluous.

Given that replacing old wiring carried out on the ragged and delivered from the plaster, wallpaper, paint and the like, the walls and ceiling, you can immediately figure out whether the old suit for the new cable channels.If possible, it is best to use them at least in part, because all the channels have been made by all the rules, and laid them in the wire last longer.

Once we decided on the scheme, it is necessary to buy all the necessary materials.Replacing electricians in the apartment - it is important, and you need quality materials.

What exactly do you need to purchase:

  • cable required length and cross section
  • corrugated or plastic tube, which will be "packed" the cable when laying
  • all necessary sockets Enclosures, switches and junction boxes
  • tools with whichworks will be conducted
Tools for forming cutting grooves
tools to excavate cutting grooves on top: wall chaser and hammer at the bottom of the nozzle to the gun (the crown with a diamond disk and rods for cleaning canals)

So cable - lately for premises prefer to copper cablebecause its electrical characteristics much better than aluminum.Although the price is appropriate, but still in such a case is not worth saving.Now, regarding the thickness of the wire: for concealed wiring is fine copper cable with a cross section of 1.5 sq.mm, and the need for an open wire thicker - 2.5 square meters.mm.But more specifically, you may well find an electrician who does for you (or check you made yourself) wiring diagram.

Incidentally, the sockets and switches is not recommended to save - Choose a reliable brand.And do not forget to immediately determine their design, because horses in midstream is not.Pick accessories that match the general interior of your apartment.

And of course, one of the most pressing issues remain: how much is the replacement of electrical wiring?To give you a clear answer can only a professional electrician, who will calculate the cost of the necessary materials and work.Many believe that the replacement of wiring your own hands may be cheaper than hiring a team of workers, but this is true only if you are well versed in the issue.Otherwise, it could happen a situation where the miser pays twice.

Replacing wiring - Getting ↑

We have everything ready to go.The scheme is made, the materials purchased, you or a team of electricians dressed in work clothes.

To change the electrics in the apartment, you should either clean the old channels to cable or make new ones in places that have been planned and are marked on the project to replace the wiring.The most common is the one and the other, as arranged by professional builders channels may well last for many years, and has slips for the new location of the sockets, switches or lamps is optional.Using old channels most preferred when replacing wiring in the Khrushchev.

What is the practical laying electric wires?

  • creation (or clearing old) channels for wiring
  • cut in the right places recesses for sockets, switches and junction boxes
  • wiring
  • assembly switchboard

So cleanse the already existing channels of concrete and other debris that is likely tohamper laying wiring.After this is done in the right places new Grooves.These grooves professionals prefer to create wall chaser whose diamond discs are most useful in dealing with concrete slabs.Of course, if you can not buy or rent a wall chaser, you can use the grinder or a jackhammer, but these tools is very difficult to make a smooth channels.

way, shtrobovanie - work terribly dusty, dirty and noisy, so it is best to warn neighbors about the possible inconveniences and attend to their own means of protection: respirator and headphones.All chipped material (concrete chips and dust) should immediately remove.For this purpose there are the so-called industrial vacuum cleaners capable of without much damage to remove such waste.And not only need to vacuum the floors, but the channels themselves and to clearly define the correct (depth, width and flatness) of the new cutting grooves.

Creating Grooves
cutting cutting grooves in the concrete wall is performed strictly vertically and horizontally

After working out at full shtrobovaniyu cut all recess, which will be located junction boxes, sockets and switches.For this purpose, punch with a special nozzle in the form of a crown of the desired diameter.Cleaning the channels and grooves make-packed scapula to the same punch.

will be fully prepared when all the passages in the walls and ceiling begin to lay the cable in the channel.Fix the wire cutting grooves in the mounting clips.Although, in principle, you can just plug the cable channels with plaster or plaster solution.As the cabling set and flush junction boxes, which are also recorded.Everything must be done according to the project developed by an electrician (circuit) wiring.Do not forget that the exposed copper wire can be oxidized very quickly, so take care when connecting contacts for the careful coating them with a layer of solder.

Laying cable Grooves
recommended wire laid in corrugated flexible or rigid pipe, but not prohibited, and no additional devices, cables if reliable isolation

And the last stage of work is the assembly of the electrical power.On separate lines of different capacity is best to install different machines, then it's easier to keep track of the state of our electrical system.

last stage of work - connecting the cable to the electrical

Another important tip - try to do everything so that after work to facilitate access to the cable anywhere - just for the future.Of course, copper cable with the correct installation can last more than 30 years, but the old woman is proruha.

most important thing - check ↑

all gathered, all combined, have established outlets and other auxiliary elements.You're the most important thing - check if all done correctly, not polyhnet whether our new scheme Christmas garlands when connected.

insulation resistance of the cable is checked Megger, which will provide high voltage for reliable testing.If everything is OK, turn machines and check the voltage presence in all the key points.

What?Happened?All!You can start decorating.

seems to be not difficult?A simple scheme - to make a project to buy materials to build Grooves to hold the wiring to connect all the electrical - and voila, ready new electrics in the house.However, even with its apparent simplicity, the replacement of wiring, there are many nuances, so make sure that the work was led by a true professional.Even if you want to do the job on their own, let them close to you pobudet consultant electrician, you never know what surprises may happen at any stage.Better to let the expert will be on hand to avoid having to redo it all over again later.Good luck in your work!
