The walls, partitions and ceilings of plasterboard have become the characteristic realities of today's construction site. The mobility of redevelopment, the dry way of erecting structural elements and decor, high repairability and environmental friendliness is far from a complete list of the advantages firmly entrenched in installation technologies from drywall. Not so long ago, builders were cautiously talking about innovation, but today the situation with podrozetniki has radically changed. Next, we will talk about installation mounting boxes used in plasterboard walls.

Selection of material and dimensions of the jar

The need for electrification of premises made of plasterboard walls and ceilings led to the creation of special accessories that allow the installation of electrical switches, sockets and other energy-saving equipment, taking into account the specifics material.

One of such accessories is the socket for installation of sockets and switches in a gypsum cardboard septum.

A wiring box (electrical) is a device that is designed to lay, connect and divide electrical cables. It is used for electrification of buildings by internal and external power transmission lines.

Electrical installation boxes are divided into two types: distribution boxes and installation boxes.

The first are designed for mounting the branch point of the wires, the second for the installation of switches or power outlets. Installation boxes, except for their direct purpose, can play the role of a junction box.

There are metal and plastic electrical boxes, in the household language called podrozetnikami. The most widely used are polypropylene boxes, due to their low cost and excellent dielectric properties.

According to their design features, the flasks are divided into two categories.

• mounting boxes for solid walls
• mounting boxes for hollow walls

The difference is that the pads used for mounting in hollow walls are equipped with a clamping mechanism that allows securely fixing the box in the wall.

Throughout the European continent, a uniform standard for the internal cross-section of the sprocket has been adopted, which is 68 mm. Due to this, the installation boxes are a universal mounting device for all kinds of sockets and switches.

Various manufacturers of electrical engineering, produce podrozetniki having slight differences in the shape, color and density of plastic. The shape and material of which the clamping mechanism is made, representing two "paws" on the movable threaded fasteners, may differ.

To install two or more boxes in one place, "batteries" of podzoetnikov are used, fastened in a single unit with special connectors. Such blocks are used in places that are used to connect a large number of consumers. For example, in the kitchen above the desk or for connecting office equipment in the office premises.

In addition to the traditionally round installation boxes, there are also boxes of square shape, rectangular or oval.

When choosing the right shape of the podrozetnik, the specific situation in which the installation will be done is taken into account.

Square and rectangular pads are used when additional cabling is planned inside the installed point. This is due to the fact that the internal volume of such boxes is larger. In fact, these types of podrozetnikov, combines the functions of the dispenser and installation box at the same time.

Oval podrozetniki used when installing two or more outlets or switches in one place, replacing the prefabricated units. It is advantageous to use them in cases where the sockets are located vertically.

Preparation of a spill strainer for installation in gypsum board, selection of crowns

To mount the installation box in a wall made of gypsum board, a number of preparatory steps must be taken.

Carry out the marking of the wall and mark on it the points where the sockets and light switches will be located. To do this, you need a pencil (or marker) and a measuring tape measure.

Strict standards, limiting the location is not, therefore, each developer has the right to choose a place.

As practice has shown, locating the power sockets too close to the floor can be fraught with a short circuit (for example, in case of water leakage from the heating system). Therefore, it is customary to install them at a distance of 20-30 cm. from the floor, in such a way that you do not have to sit down on the floor for the inclusion of domestic electrical appliances in them. Convenient is considered the outlet, which is easy to get, bending over.

An exception to this rule is the connection points for computer and television networks. Often they are mounted in the last place and the cables are laid in the already assembled floor skirtings. Inside the skirting, there is a cavity designed for pulling additional network lines. Then the plinth is cut and a socket with special connectors is mounted in it. This is allowed, since this type of cable passes through itself so-called "weak currents" and short circuits are not terrible for him.

On the kitchen "apron the rosettes are raised by 15-20 cm. above the desktop.

Switches of lighting are located, as a rule, at a height of 90 or 150 cm. from the floor and 15-20 cm. from the edge of the door frame.

When performing markup, it is recommended to use a building level or a laser, especially if several outlets are located in one row.

For installation of blocks from a number of switches or sockets, it is necessary to note the centers of future circles at a distance of 71 mm.

Dipstick should be brought into working condition by adjusting the location of the clamping device. If the wall consists of 2 layers of plasterboard, then the distance between the rim of the podzrozetnik and the foot should be more, Otherwise, the box will not be installed. The distance is easily adjusted by unscrewing the fixing screw. Therefore, in the beginning of work it is best to take the clamping paws to the maximum distance from the upper rim.

Perforated holes are located at the sides and at the bottom of each mounting box, the plastic on which must be broken according to the planned connection. Theoretically, one cable should be pulled into each hole, but in practice the installer decides on his own how many holes it needs to connect.

In addition, before starting work, it is necessary to connect the subwindows to "batteries if any. This is done with the help of plastic connectors, which are attached to the side lugs of the box (rectangular shape). In the shops, the connectors are sold separately and are not included in the kit with podrozetnikami, so they need to stock up in advance.

To drill a hole under the mounting box, you need a crown with a diameter of 68 mm. and a screwdriver or a drill (perforator). If they are not available, the hole can be carefully cut with a construction knife, after drawing a circle in the planned location. But since the form of the hole depends on the reliability of fastening, it is better to apply the crown to the tree.

You can not also cut a hole with a knife if the wall is located in the bathroom or in the kitchen and is tiled. In such cases, use a crown with a diamond cutting edge (for concrete).

Step-by-step installation instructions

If the pads and tools are ready, and the markup is applied to the walls, the installation procedure does not take much time and effort.

The first thing to do is make a hole.To do this, install the crown on the screwdriver (drill, perforator) and at medium revs, resting the drill in the intended center, a circle of the desired diameter is drilled.

Since under the drywall cable is laid, which will be connected to the outlet, you need to drill slowly, making sure that it does not damage the conductor. As soon as the crown passes through the thickness of the gypsum, it can be removed from the hole.

After that, you need to get the cable out of the wall and insert it inside the jar.Accordingly, if there are several cables, all of them at the time of fastening the installation box to the wall, should be inside the juniper.

If this is not a blind wall, but a partition that is wired with plasterboard only on one side, it is not necessary to withdraw the cable, as there is still open access from the other side.

And the last, final stage - fixing the box in the wall.To do this, the insert is inserted into its place, and the screws of the clamping device are tightened. The main thing is not to overdo it, because excessive tightening of the screws can damage the threads in the plastic "body" of the box. It is best to set the force controller on the drill to low values ​​(3-4 divisions), and the final tightening to be done manually.

The final stage of work

At the final stage of the work, adjustments are made to the installed podzroetnikov. Possible defects are eliminated, the dust is removed, and cut to the desired cable size.

If there are a lot of cables, then when cutting, you need to remember about their marking. Labels with signatures are transferred to a new location, so that later there would not be confusion.

If during the drilling and installation of a piece of gypsum board was formed, it must be liquidated with plaster ("Uniflot etc.). To increase the strength and prevent cracking, the place of the putty is pre-glued with a net bondage.

Criteria for selection of junipers

To get out of the ocean podrozetnikov, which are located on the shelves of stores, choose the model that meets the requirements, you need know its exact size (diameter and depth), shape (round, square, oval) and purpose (for concrete, drywall or hollow brick).

If all this is known, it remains to be decided only with the manufacturer that produces this electrical device. Naturally, trade brands should be preferred, whose products are well-known and well-established.

Here are some examples of the most famous models that are successfully applied at a professional level.

• The SZEZ podzroetnik is produced by the Russian manufacturer. Excellent proved himself in electrical work, is characterized by high-quality plastic, high degree of fire safety.
• The installation electrical box HEGEL 68x60 mm. KU 1205 is a brand of the domestic company, on the Russian market since 2006. A distinctive feature of the model are metal clamps.
• Chest of Chinese manufacture "Dr. HD "(ID9288) - in spite of not very flattering reviews about products of Chinese production, this product is distinguished by a high level of quality. The box is square in shape and contains in itself all the positive characteristics inherent in podrozetnikam with this form.
• The electrotechnical box 2332UJBS is a product of the company ABB (Sweden), made of high-quality polypropylene. The brand is well known for its professional electrical installation equipment.
• Sleeve GUSI ELEKTRIC 68 mm. The product of domestic production, pleasantly different price. Quality meets world standards.

Installation of the installation box, due to the simplicity of its device, is available to every adult person. The procedure does not require special skills or knowledge. The only necessary condition, if the installation is done during the repair work, is a complete disconnection of the electric current supply. Before starting work, it is necessary to disconnect the power outlet and additionally check the absence of voltage by means of an indicator.
