How to make a hidden wiring?

drywall What are the advantages of this method?

Hidden wiring is used during the capital repair of housing or replacement of wiring for a new, more powerful.

The advantage of concealed wiring within the walls is as follows:

• The electrical wiring will be hidden under a layer of plaster or in plasterboard partitions.
• Increased fireproof housing, if the walls are concrete, not wooden( or plaster).This is due to the fact that when the insulation is ignited, the fire will not spread further, due to the lack of oxygen and flammable materials.
• Extended service life of the mains connected with reliable protection of the conductor from ultraviolet and mechanical influences.

Among the disadvantages should be allocated the complexity of installation, compared with the open method, as well as the complexity of repair and maintenance of hidden electrical wiring. The last two minuses are connected with the fact that all the wiring elements are hidden under the layer of plaster and for access to them the destruction of the walls will be required.

To summarize, it should be noted that for capital housing this option is more correct and reliable. As for the bath, garage, log houses and other buildings, it is recommended to conduct an open wiring.

Step-by-step instruction for wiring

So, now we will consider how to correctly make hidden wiring in a brick house with your own hands using the example of small instructions.

Create the scheme

The first thing you need to do is create a scheme that marks the route of the cable passing through the walls, places of installation of outlets, switches and junction boxes in each of the rooms. Based on this scheme, we will calculate the materials well and, in fact, install the hidden electrical wiring.

Recommendations for the design of the circuit:

1. The cable must pass strictly vertically and horizontally over the surface. The only rule is that the distance from the floor and ceiling should be 15-20 cm( for convenience of repair and installation of concealed wiring).
2. The height / location of the switches and sockets is not standardized and is usually chosen based on individual conditions. For example, in the kitchen the socket can be installed above the countertop, and in the hall - behind the TV.The junction box is installed at the entrance to the room.
3. The distance from the heating batteries, piping and ventilation ducts should not be less than 50 cm( according to PUE).

Preparing tools and materials

At this stage it is necessary to calculate, according to the project, the number of outlets, switches, and the length of the conductor in order to perform the installation of concealed wiring in the walls. First, you need to calculate the cross-section of the cable to select the most suitable core diameter. If this item is neglected, there may be a danger that the conductor can not withstand current loads from powerful electrical appliances. After that, select the most appropriate types of switches and sockets for rooms, for example, in the bathroom you need to use waterproof products( for security reasons).

The minimum set of materials is as follows:

• sockets;
• switches;
• spoilers;
• junction boxes;
• cable;
• protective plastic corrugation( optional);
• connection terminal blocks;
• insulating tape;
• gypsum solution.

As for the tools for wiring installation you will need the following:

• shroud, Bulgarian or perforator( for strobing walls);
• chisel and hammer;
• multimeter;
• stripping tool or knife for an electrician;
• set of screwdrivers;
• building level;
• pencil;
• trowel.

Having prepared all the necessary kit, we can start installing hidden electrical wiring in the house with our own hands!

Shtrobim wall

The first thing you need to do is to touch the walls if the installation will be done in a brick or panel house. Before shtrobleniem need to put on the surface of the walls markings, which you will navigate during the creation of depressions. A very interesting technology for marking, we provided in the article the installation of electrical wiring in the house, where a chalk painted rope was used.

When the walls are marked, we take the bulgarian in our hands and begin to cut out the groove. This is done quite simply - two parallel lines are cut at a distance of 3-4 cm from each other. After that, the chisel and the hammer knock out a strip, which will be a ready shot. The depth of the slick for concealed cabling depends on the cross-section of the cable and the presence of a protective corrugation. In any case, the depth should be chosen with a small margin associated with the application of a layer of plaster to level the wall.

Instead of the Bulgarian, you can use a special tool - shtroborez, which accurately and without dust will create suitable depressions. The problem is that the price of such a tool is quite high and in order to once install a hidden electrical wiring in a private house it does not make sense to buy it. However, in this case, you can find a way out - to make a shroud cutting yourself!

We recommend you to view the master class which shows how to bend the walls for wiring:

Installing the

chimneys At this stage, everything is simple - you need to prepare holesto perform the installation of podrozetnikov and junction boxes under concealed wiring. So that they reliably "sat" in their places, use a plaster solution that reliably grabs the plastic against the concrete. The edges of the products should be flush, so that there are no problems with the decorative decoration of the walls.

We lay the line

Now, when the junkets and the junction box are installed, it is necessary to conduct a hidden wiring through the shtroba. First, cut the cable into suitable lengths( for example, from the box to the switch), leaving a small margin for the connection of the strands. Next, we place the segments in the recesses under the ceiling and in the walls, after which we grab them with a plaster solution. Also, the cable can be carried on its own in the floor, but this kind of installation is not very good, because the repair and maintenance of internal electrical networks will be difficult.

Regarding protective corrugation, the question is individual, you can not use it. The purpose of the corrugation is to provide additional protection against mechanical damage. If you choose a PVA labeling wire, you do not need to worry about additional protection, becauseisolation of this conductor is quite reliable.

When the line is picked up by gypsum in some places( as shown in the picture), it is necessary to call the hidden wiring to check the correctness of all connections, as well as the operation of the power network. If it's okay - we put the wall in.

That's the whole technology of installing hidden electrical wiring in a brick house and apartment with their own hands. As you can see, there is nothing complicated, the main thing is to observe the color coding of wires when connecting wires, and also to do everything carefully. After the work is completed, the sockets and switches are installed, and the protective switchboard is installed on the switchboard, after which it is possible to proceed to installing chandeliers and arranging the rooms.

The only thing I would like to tell you about is plasterboard walls, becauseabove, we provided instructions on the hidden installation of wiring in concrete and brick, which is much more complicated and is used less and less today.

If you decide to conduct electrical wiring in a wooden house( shield, frame or from a log house), we recommend you read the article to which we referred. The importance of the issue lies in the fact that when wiring the cable over combustible substrates, many nuances must be considered, which we considered in detail.

Features of work with gypsum board

When installing concealed wiring in gypsum cardboard, things are much easier, becauseIn this case, no strob does not need to be done. The line is carried out under sheets of plasterboard partitions between the structure of the profiles, as shown in the photo.

The problem is that if the insulation of the conductor is damaged, a leakage current can occur on the profile. The result of a leak is the probability of electric shock to a person. To avoid this, it is recommended to place the line in the corrugation, and better - the plastic pipe. In places of installation of junction boxes it will be necessary to cut out in the gypsum cardboard the special hatches for quick access.

That's all I wanted to tell you about how to conduct wiring in concrete and plasterboard walls with your own hands. As you can see, the installation of a hidden electrical wiring in a brick house and apartment does not represent anything complicated. We hope that the information was useful and understandable for you! In order to visually see the whole process, we provide a detailed video instruction:
