Rules for the installation of electrical wiring in a wooden house

The installation of electrical wiring in a wooden house by one's own hands requires seriousness and responsible approach.

This means that you can not only ignore safety rules, but vice versa, you should strictly follow them.

It should be remembered that wood is a readily inflammable material and even a slight inaccuracy made during installation can cause it to cause a fire.

Installation of electrical wiring in a wooden house has its own characteristics, which is due to the specific nature of the material from which the building was built.

Among the fire hazard faults is:

• short circuit;
• cable line overload and, as a result, its overheating.

To do everything right, it is better to consult with professionals, and if this is not possible, then you need to carefully study the appropriate technical manual or watch the video.

The basic rules of installation work include the following stages:

• design - as a rule, electrical work is carried out according to a pre-established scheme, previously approved by the relevant authorities;
• preparation of tools, materials and components;
• marking and laying of the cable line;
• installation of distribution boxes;
• installation: external wiring, buried wiring, sockets and switches, lighting fixtures, flap, earthing circuit;
• work quality control.

How to design a wiring?

If you are not sure that you can make the design of the electrical wiring yourself and calculate the exact amount of materials, then contact the specialists for assistance.

At this stage, technical literacy is very important, since without compliance of the project with the established standards there will be no permission for its implementation.

Typically, a building plan is used to create a wiring project, which specifies the following parameters: the layout of all electrical points, the method and location of the wiring.

When designing a wiring project with your own hands, it is recommended to take into account such rules:

• All electrical points of the circuit must be installed in accessible places;
• All switches should be positioned at the same height, but not less than 1 m from the floor and on one side of the door, to the right of the entrance. It is impossible that the switches are behind the furniture or were covered with interior items. Therefore, experts recommend to determine in advance with the arrangement of furniture and equipment;
• The location of the outlets should be comfortable without using extension cords. According to the regulations, the sockets are installed within 40 cm of the height from the floor, but not lower than 25 cm. Next to metal structures, plugs are forbidden, the minimum distance between them should be 50 cm;
• The cable is installed exclusively in straight lines, either horizontally or vertically - at a distance of 15 cm from the ceiling, door and window openings and floor. Turning the power line is possible only at right angles;
• The switchboard is installed in the corridor at a height of not less than 1.5 meters, so that children can not reach it;
• The wires are connected only through junction boxes.

After the design of the electrical wiring is ready, it must be approved in the State Energy Inspection. If the project is approved, it will be possible to connect to the power grid within 5 days.

Preparing for installation work that will be required by

It is very easy to determine how many components are needed for electrical wiring with your own hands, guided by the wiring diagram.

As a rule, these are tools for the installation of wiring - a screwdriver of various types, configurations and diameters, pliers, as well as a knife, hammer and voltage indicator.

Handles of all tools must have a protective insulation coating.

Three-core electrical cable. To operate in a wooden house use a copper cable brand BBG.

The numbers usually indicated after the letters of the cable mark indicate, respectively, how much in the cable the conductor and what its cross-section.

The cable cross-section is calculated based on the total power consumption. But if the cross section for the declared power is not enough, the cable is put in 2 lines.

Electrical switchboard - it's the safest thing to use a metal switchboard in a wooden house. The size of the device depends on how many cables will be connected to it.

Switches and sockets - the required quantity is determined by the wiring diagram.

In the selection of components, it is necessary to be guided by the type of electrical wiring - when hidden, use built-in switches and sockets.

And if the project provides for retrofitting, then it will be suitable components for the overhead type.

For wooden houses, experts recommend paying attention to retro style accessories, with ceramic bases and contacts made of bronze or brass.

According to the regulations, electrical wiring in wooden houses can not be hidden, it is prohibited. But for a cable of external conducting it is possible to apply special pipes.

Electric meter - the best option - a two-rate device. And junction boxes, self-tapping screws, electrical tape.

Wiring. How to start the installation?

To get a minimal idea of ​​the upcoming process, we recommend that you watch the thematic video.

The installation of electrical wiring in a wooden house with its own hands is preceded by the installation of a cable from the outside.

For the implementation of this process, the methods of air and underground concealed wiring are used. After these works, you can start installing the open wiring.

The main cable in the wooden house must be as open as possible.

Therefore, to maintain the aesthetics of the interior, specialists use special cable channels and plinths.

Despite the fact that the wiring seems hidden, access to it is not difficult. To insert a cable into the building use a metal sleeve.

Before starting installation and subsequent work, the cable is pre-cut into lengths that correspond to the distance between the electric points, but with a margin of 15 cm.

The wires are then laid in channels and fastened to the walls by marking, as indicated in the design. In this case, the cable channels are still open.

Next, the junction boxes are installed. Their purpose is to distribute the cable evenly over all rooms in the building.

Therefore, the distributors are installed in the branch points of the main cable.

To connect cable lengths in junction boxes, several methods are used by one's own hands, but the simplest and safest of them are PPE caps.

They are made of plastic, not subject to combustion. For this, the ends of the cable are cleaned and screwed into PPE.

Depending on the total number of twisted strands and their cross-section, the caps are distinguished by color and number, the larger the number, the more wires can be connected with it.

An even simpler way to connect the wires is to use electrical tape.

Subsequent stages of installation work

To install sockets in a wooden house, it is sufficient to lay an insulation layer between the wall and the socket housing, on which to attach the outlet on top.

If the cable is three-core, then all cores are used for connection. Install switches and lights in the same way.

For the safety of further operation, it is very important that the fastening of the contacts is of a high quality.

Mounting of the switchboard and meter is made taking into account the power consumption limit.

The final step is to check the circuit and the insulation resistance. To do this, use a megger.

What is a decorative wiring?

Due to the fact that in wooden houses the laying of concealed wiring is prohibited, many owners resort to laying retro wiring.

That is, instead of all known hidden electrical wiring, they set up original decorative wiring in the once forgotten retro style.

Classical retro wiring is a stranded single-wire wires that are attached to the insulator during installation.

In modern design, twisted retro wires have copper cores and a silk outer shell impregnated with a protective compound.

This method of open wiring is not only fully approved by the relevant authorities, but it is also fully justified from the point of view of modern consumers.

Unlike hidden electrical wiring, the retro style installation is carried out after finishing the premises.

For retrofitting themselves using very modern materials - special rollers made of plastic, which are installed on the line of wiring every 50 cm.

These retro rollers are attached to these small rollers.

You can get acquainted with the details of retro wiring installation by watching the video. In
