Repair - it is a necessary but problematic. Many owners of homes or apartments when instigate repair work are often faced with the problem of finding the junction box.
Look for it under a layer of plaster, wallpaper or even Plasterboard is no easy task. Well, when the owner of a house or apartment himself conducted the installation of electrical wiring or at least present at this moment.
What can we do to people who entered the apartment where the wiring has been carried out before them? In fact, there are several effective ways to search for the junction box, look at them in more detail.
Junction boxes in the old-style apartments
- Khruschovka. In the 60s of the last century in the Khrushchev boxes were made of metal and they closed very cumbersome cap to disguise that it was difficult for finishing materials. Find a metal box and can be visualized with the naked eye. Usually in the Khrushchev, they were mounted at a distance of 15 cm from the ceiling level. Also iron has rust property, oxidation necessarily manifest itself on the surface of the fabric;
- Breznev. In high-rise buildings of this type of technology and methodology mount junction box is different. Mounting carried out at the junction between the wall and the ceiling and closed galvanized sheet metal, forming the void. It would seem, to find such a structure without any problems, but the whole dilemma lies in the fact that this list fairly plastered with plaster, which creates a problem of search. For successful detection, you can use special detectors, alarms or lead from socket indicator screwdriver, guided by the light indicator light;
- stalinkas. In such houses search junction box will be based on prostukivanii wall at a height of 2.5-2.9 meters, as in the case of successful detection will hear a distinctive thud.
Search junction box in the apartments of modern type
The houses, built in the 2000s, and modern buildings, used boxes made of plastic. They are no longer masked by a thick layer of plaster, and simply pasted neatly wallpaper or other finishing materials.
The most difficult situation is the search box under the drywall. The problem is that the gypsum board sheets are mounted on a metal profile, and use a magnet to search for postings will not work. The only way out - the use of the detector-alarm.
If you want to find a box from the wall outlet, then connect it to the mains filter, which should also connect multiple high-power appliances. Turn on the power strip, then the tools and through the use of a conventional screwdriver indicator going upwards from the outlet, as the intensity of the luminescence indicator obtain precise location box.
There is another method for determining the distribution box, but it does not provide a 100% guarantee. In this case, we hope that its installation was carried out based on the requirements for electrical work, according to which, the box set to 15 cm below the level of the ceiling (see. figure below).
