Laying cable in drywall: features, work order

During the overhaul is usually made replacement of all elements, including the wiring. It depends on the work of electrical appliances, and today there are many in every home. In order to properly lay the wiring, you need to take into account certain nuances, for example, how to draw conclusions for connecting sockets in drywall.

Consider the features and order of such work.

In modern production for the manufacture of electrical wires mainly used copper. The finished wire is placed in an insulating sheath.

In this case, the handset does not interfere with the installation and prevents damage to the cable, which will make it possible to avoid a short circuit.Also, such a sheath can protect the wire from small rodents, which is especially important in some household premises.

Also for this purpose PVC (PVC) pipes or special hollow cables are sometimes used.made of plastic. They are not so convenient at assembly, they are difficult for laying in hard-to-reach spots.

The method of wiring depends on how the plasterboard finish is mounted. The method without installing the frame is used quite rarely. In this case, it is necessary to grind down the surface of the main wall, and place the wire into it. For places in which switching and switching facilities will be installed, holes must also be prepared. After that, the cable is attached to the wall with special clamps.

In the frame method of plasterboard plating, wiring under it can be carried out on the wall (as in the variant described above) or directly at the base of the finish, using the frame stands in the form of a cable support. To do this, you can purchase special slats, in which there are ready points for posting. Fastening in this case is often done with a plastic cable tie.

The first thing to do before starting work is to plan the layout of all the inputs and outputs for the attachment points of sockets and switches. Also, be sure to plan where and how electrical lines will be laid. Use two methods: wiring on the ceiling and along the walls. The choice of method depends on whether the ceiling overlaps or not.

First, the frame is made of a metal profile using the standard method. In the necessary places are installed slats with special holes for the cable (if such were purchased).

In the next step, it is necessary to fix the distribution panels in each room. To attach them to the wall, you can use the most common dowels or screws for drywall.

In the next step, power lines are laid. To begin with, clamps or clips are fastened along the entire length with screws, which will fix the cable previously enclosed in the corrugation. Fastening ties can also be used as a fastening material.

In the frame racks need to drill holes. Through them will be stretched horizontal cable.

Be sure to draw conclusions for connecting sockets and switches. As a rule, sockets are placed at a height of about 300 mm from the floor, and switches - 800 mm. It is recommended to make marks on the floor near the place where they will be placed, so that later they can be easily found under the drywall.

Upon completion of laying the wiring frame is sheathed. Then you can begin to drill the holes for the glasses into which the sockets are installed.

This method is used if the drywall is mounted on the adhesive from plaster for installation without the use of a frame. In this case, the space under the upholstery will be small, so the wiring lines and sockets must be recessed into the wall. For this, holes for wiring are made in the wall.

Gouging is the cutting of longitudinal grooves (grooves) on the surface. For this you can use the most diverse hand tools: chisel, hammer or chisel. This can also be done using a grinder, wall chaser or perforator.

For more convenient stroking is necessary, as well as in the frame version, you must first transfer the entire wiring diagram to the ceiling and walls, after which you can begin to carve the surfaces. When working with concrete, foam concrete or brick, it is better to first make longitudinal cuts (channels along which it is necessary to carry out gouging).

Along the markings made, the lines are broken down for wiring. At the same time, in places where sockets, switches and distributors are installed, recesses of the corresponding diameter are made. If the house is wooden, then make such grooves better chisel. After the main lines are broken, junction boxes are installed, and the cable chosen in advance is laid along lines in a corrugated pipe, securing it with plastic clips.

After finishing the laying of wires begin to mount the drywall. Wherein it is necessary to take into account the location of the laid cables, so as not to damage the wire with screws.. Having finished the installation of drywall in the places where the switches and sockets are installed, you need to drill holes of a suitable diameter and install the socket, leaving the wiring terminals outside for further connections.

The implementation of wiring in rooms with high humidity, which include a bathroom, has its own characteristics.This is due to the fact that wet surfaces are an excellent conductor, an electric current can pass through them.

This is what causes the special wiring requirements:

• Electrical switch and junction box must be installed outside the room (bathroom).
• Installation of sockets is carried out no closer than 65 cm from water pipes.
• Indoor waterproof appliances must be carefully grounded.
• The power supply line of the devices in the room is connected to a separate automatic fuse.
• All grounding tires are connected together to equalize electrical potential.

When planning the installation of wiring in the false ceiling with your own hands, it is necessary to take into account that this method is somewhat different from the installation inside the walls. In particular, the wiring to single lamps mounted on the upper edge of the walls of the room. Holes are drilled in sheets of plasterboard through which the cable is laid. Through them you can stretch a few meters of cable.

In general, the installation of hidden wiring in drywall requires special attention and consistent implementation of all stages. With proper consideration of the network load (especially 380 volts), selection of high-quality components and careful installation, the assembled circuit will serve for a long time and efficiently.
