Junction box or junction box is usually called special boxes. They are closed with a lid, and on the sides there are special holes in which you can lay any number of wires. The mounting box is most often made of plastic. You can purchase such boxes for hidden or open wiring.
How is the installation of the box?
Such structures are installed directly on the walls. In any case, if we are talking about open electrical wiring. If the latter needs to be installed hidden, then everything is mounted deep into the wall. The junction box should most often be placed so that the wires can be accessed at any time. Thus, the outer part remains visible. When connecting the wires for the first time, this must also be taken into account. Any electrician begins repairs when a problem occurs precisely from the junction box. It is necessary to take into account this possibility even when performing the installation of this structure.
How can the system be organized?
Wiring is often divided into several trunk lines to ensure a reliable and uniform distribution of electrical energy on the site. There is no connection between the lines. Your own power cord is laid in each separate room. Other consumers of electricity are connected to it after.
A height of twenty to thirty centimeters from the ceiling is the most suitable for mounting a device such as a junction box. This device can be hidden behind plaster or behind ordinary wallpaper. Thanks to this, the appearance of the room will not be spoiled. But you should immediately remember where the box is.
Mounting box for socket - what are its features?
In general, the mounting box can have different sizes. When laying electrical wiring in an apartment, the most commonly used sizes are 40-45 millimeters and 60-65 millimeters. This is 68mm outside diameter, so the holes for the box are best done using a hole saw with a 70mm diameter.
To get whole blocks, you can connect several boxes together at once. This makes it possible to install several sockets under one frame at once. 71 mm - this is the value of the center distance between the boxes when they are connected into a whole block. So connecting cables, sockets becomes an easier process.
Some tips for mounting the box
The main thing is to completely de-energize the apartment before installing the box and the wires suitable for it. Formounting the device in a recess, you need to prepare a special solution. Plain water is enough, as well as alabaster or building gypsum. The consistency of the solution should resemble sour cream. After breeding, you must immediately add the material to the recess. The distribution of the signal will largely depend on this, so the quality of these works should be given special attention.
It is necessary to align the box and make sure that it practically does not go beyond the level of the wall.
