The socket is not only an essential functional element of the wiring, which serves to connect various household appliances, but also an important detail of the interior. The work and its neat appearance largely depend on the literacy of the installation of the sockets. To perform the correct installation, you need to take into account some of the nuances in the work. First of all, you need to know the depth of the rosettes.
Types of Sockets
The box for the outlet is selected based on what material the wall is made of, into which it will be placed. Therefore, there are the following types of products:
- Boxes designed for installation in brick, concrete, and aerated concrete walls, they are fixed with a mortar.
- For walls of drywall, plywood, they have special fastening structures that are designed for installation in the wall.
- Sockets for wires in the standard version are round, but there are oval and square products. The depth of the undergrowth is important in that it allows you to lay the necessary supply of wires inside it.
During installation, it is necessary to choose the correct box size. The standard size of this product is 45 by 68 mm, and the depth of the undergrowth, respectively, will be 40 by 65 mm.
The most popular and safe boxes are made of special dielectric plastic. They are used in all types of structures, except for wooden ones. For such buildings, metal sockets are intended.
How to install a wall socket in a concrete wall
Work begins with marking the surface, after which it is necessary to make a hole for the socket. In concrete and brick structures, socket boxes are fixed with a solution of gypsum or cement. Therefore, it is necessary to prepare this solution.
In order to make a hole in the surface, it is necessary to take a drill and a special crown on concrete. After the work is completed, we remove the remaining concrete from the place obtained. With a brush we clear a place for a sap from dust.
Now you need to fill the recess with the solution, put the box in it and fix it, lead the wires through the special holes to the outside. The depth of the sockets for concrete is usually from 67 to 68 mm. Therefore, the depth of the recess in the wall by 5 mm should be greater than the depth of the box, since it is necessary to take into account the place for the solution.
The solution must be prepared before installing the box, as it quickly hardens.
We install a sock in drywall walls
Installing a box for outlets in drywall does not require the use of a solution, there are special fasteners on the products. To make a hole in the wall, you need a drill and a crown on a tree.
When everything is ready, put the socket in the wall, put the wire into it, and install the box so that the bolts are parallel to the floor. Next, those bolts that are recessed must be tightened. The box is fixed in the wall, two other bolts are needed for attaching to the outlet box.
The depth of the drywall for the drywall allows you to leave a supply of wire of two diameters in this box. When folding these wires, they must be placed without creases, if the margin is 10 cm, then you can fold it in half, but so that they do not touch each other.
The most common box sizes
The most important characteristics on the basis of which the size of the boxes for sockets is determined is the diameter and depth. These sizes correspond to the size of plugs and sockets sold for sale.
The main diameters are 60, 64 and 68 mm. At the same time, the diameter of the sockets of 68 mm is most in demand.
At the same time, the depth of these products is 40-60 mm, it is chosen depending on the purpose. Some sockets are used as junction boxes. Then they take the deepest boxes, in addition to the wires, they also place the connecting terminals.
When choosing a socket, the depth of the undersocket is determined. The minimum value of this indicator must be observed so that the wires are located compactly and without touching. This depth is 40 mm.
Sizes of boxes for sockets
To do this, use a crown of the required diameter and depth. The material of the crown depends on the type of wall. Drilling a hole under the socket is made at high speeds, which leads to the most accurate holes in the wall.
Nowadays, European-type sockets are often used, the depth of the standard undergrowth of 45 mm is suitable for them. The installation of this box for the outlet is identical to all other installation methods, the same crown is used, which is selected depending on the wall device.
The maximum depth under the stalk
Sometimes you have to face such a problem, when the wall device has a friable structure or multilayer, such walls can consist of:
- gypsum and boards;
- clay and wooden floors;
- bricks and boards.
This wall structure is most often found in old residential premises, the thickness of the first layer of the wall could reach 70 mm, then brickwork went on. Initially, an ordinary tin can was intended for such walls, with cut openings for wires, it was practically recessed into the wall, attached to a cement-lime mortar.
The installation of such rosettes lasted more than a day, due to the expectation of when the solution solidifies, and the rosette is fixed in cement. Only after that the outlet was attached to the wall.
Soon plastic boxes for sockets came to replace cans. Currently, they are most in demand.
The most important question is when to make holes for sockets
This question arises among many builders and repairmen. There is only one answer - marking should be carried out before finishing work. Next, you need to make holes for the boxes, in the process of plastering they need to be left in place.
After the wall is plastered, it is possible to install boxes under sockets. This is if the installation is done in a concrete wall. When the box is already installed, you need to carefully cover the outside with all the flaws so that the surface is flat.
If the socket boxes need to be installed in a plasterboard wall, it is necessary to make a marking, then the holes for these boxes, and the boxes themselves can be installed after the wall is plastered.
In the event that the box under the outlet must be installed on a surface of ceramic tile, then before the tile is laid, it is necessary to make markings, then a recess for the socket. Wires are also laid by electricians before facing work.
After the tile is laid out, holes are made in places marked with a diamond crown. During operation, the crown must be lowered into the water. After the recess is prepared, a solution is placed in it, then the wire is removed, and the box is fixed in the wall.
Conclusion
So, we examined what the depth of the rosettes should be.
If the installation is done correctly, thanks to the installed boxes, the sockets will be firmly held in the wall and will not become loose during operation. The wall will remain intact, and its appearance will not be spoiled by cracks and broken sockets.
