And well, if you are doing the wiring and know where the boxes. And what if you bought this house or apartment and have no idea about their location. Do not redo all the wiring. In this article I will tell you how to find the junction box in the wall.

It is our main task as accurately as possible to determine the location of the box, because if you look for it by "educated bet", in this case, will have to repair most of the walls. A major research challenge lies in the fact that we all strive to make a beautiful renovation in the house, and spoil the whole box bulging aesthetics, so we strive to hide them as much as possible. Therefore, we start looking with the mind.

Getting search

So, let's look at the main options that will find a box with minimal damage to the wall:

Let's first look at the house type "Hruschovka". When erecting such buildings distribution boxes were made of metal and the cover (closing box) has a characteristic-eared clip. They are pretty hard to hide so many owners simply just sealed the box of wallpaper. In this case, the wall still remained clear hill, the aforesaid very easy to find on the wall.

If your house is named "Breznev" in such houses junction box located at the junction of wall and ceiling. In this niche banal closed galvanized iron sheet. Then the builders walled up the place pretty decent layer of putty. Therefore, in this case, you can not do without specialized equipment. For example, Woodpecker device pinpoints the location of this niche. After all, it 's settings allow to find the wires at a depth of up to 7 cm.

If you "stalinka" then find the bus can be found in the following way: take a screwdriver and tapping the back of the wall strictly above the old wall outlet or switch, and at a height of 2 - 3 meters will hear a dull sound, that there is hidden box. Of course, it is possible and the deviation from the vertical, but it usually does not go beyond 30 cm.

Just do not write off the standard scheme. After all, rules for the implementation of the wiring, there are already quite a long time, and the bulk of electricians are trying to maintain the standard. Therefore, based on this fact it can be assumed that the box is located at a height of not less than 15 cm from the ceiling.

Modern builders of apartment buildings are mainly used plastic boxes, and all of them as well as in the Khrushchev stick out, so they are also not difficult to find.

In case, if the walls covered with plasterboard, then this option can not do (again woodpecker help us) without instruments.

In case, if you are convinced that the box cover is metal, it is possible to take a magnet and use it to find the box.

But in panel-type buildings, wiring, and the box itself is on the minimum depth, so they can find banal display with battery screwdriver. To do this, simply take the sting of his hand, and the back of the drive on the wall and where the LED lights brighter and the wire lies, and there may be leading him to enter the box.

Important. For a more reliable determination of the need to run wires for current. To do this, if you go from the switch, turn on the lights. And if the "dances" from the wall outlet, then plug the it in any load.

These are all basic guidelines for the determination of the junction box in the wall. I hope my article will be useful to you. Thanks for attention.
