How to conduct an open wiring in the house?

What are the advantages of the method?

Open wiring on the walls is often used not in houses and apartments, but in the garden buildings in the country - garage, hozblok, bath. Although if you try and choose the right materials, even in private houses and modern apartments, this option of wiring will be in favor.

Advantages of open wiring are as follows:

• is a simpler and faster installation, which even a novice electrician can easily handle;
• will require less tools and materials than when creating concealed wiring;
• from the junction box you can at any time bring a new group of wires( for example, if you want to install another outlet);
• in some cases, this option positively affects the interior of the room( for example, if you use a mount in porcelain rollers and insulators in the bath);
• repair and maintenance of the line can be carried out without disturbing the decorative decoration of the walls.

At the same time, the disadvantages of installing the open wiring with your own hands is an increased risk of fire, limited in the conditions of use( you can not use it in the kitchen) and a shorter life of the power network. The last drawback is connected with the fact that the track is subject to mechanical damage more than if it is held in the walls. To solve the problem with a fire, it is recommended to carry out a non-combustible VVGGG cable on a combustible base( for example, in a wooden house).

Wiring instructions for

To date, there are several options for how to make an open wiring with your own hands. The most popular are the use of special plinths, cable channels and corrugations. To make retro electrical wiring in the house you can use a fastener on porcelain insulators, however this is a completely different topic for which we have singled out the whole article.

First you need to create a wiring diagram of the rooms, determine the locations of the distribution boxes, outlets and switches. Further, the level of construction and a simple pencil on the walls draws straight lines, which in future will need to conduct the most open wiring.

At the preparatory stage, according to the scheme, the number of all elements and the conductor diameter of the conductor are counted. It is recommended to carry out the calculation of the cable cross-section independently, so that later the wiring failure can not occur if the network is overloaded. So, let's look at each of the ways of installing a home network open-ended.

Cable channels

The most attractive way of external wiring is using cable channels, which are narrow plastic boxes shown in the photo. Surely, such products you could see in offices, commercial premises and even some private homes. The fact is that there is an assortment of goods in different color solutions that can fit even the interior of rooms.

Fastening the cable channels is quite simple with the help of glue or screws. The first method of installation is used in the event that the surface of the walls is perfectly smooth and even. The glue is applied to the adjacent wall of the box, which is then pressed down in the right place on the wall.

Our advice is to press the product against the wall and immediately remove it. On the surface will remain the glue that was on the back of the cable duct. Wait a few minutes for the glue to froze a bit, then squeeze the product again. This time with a little effort to ensure reliable adhesion.

In addition, you can drill through every 30-40 cm holes, drive dowels into them and screw in the screws. On gipsokarton it is necessary to install the open electrical wiring with a dowel-butterfly. At the corners and joints, additional accessories are used - stubs, corners, connectors, which are simply connected together. When the entire "skeleton" of the channels is assembled, go to the conductor. In places where the wires are connected to a junction box, sockets and switches, the insulation is cleaned by 10-15 mm.

Eventually, all the "points" are connected, the open wiring is conducted by a multimeter and the electrician is connected to the switchboard of the room.

Electro technical plinth

The second option is not less popular and simple. To date, special skirtings are available, inside of which there is a camera for the open installation of electrical wiring. This option allows "to kill two birds with one stone" - to make the wiring unnoticeable and at the same time functional.

All you need is to buy such a plinth, fix it to the floor and put the wiring in it. In the places where the cable exits upwards( for example, for tapping to the outlet), it is necessary to drill a hole and pull out the required conductor. Very often the electrical skirting board is used in combination with cable ducts when wiring open-wire in a panel house and a one-room apartment. If you need to stretch the line through the doorway, you will already have to drill a hole in the wall, and it is obligatory to install the open electrical wiring through a partition in the protective polymer pipe, which is required by the rules of the electrical installation.

Corrugated pipe

This method of open wire routing is practically not used in residential premises. It can be used in economic buildings, as well as when installing street lighting, because of an unattractive appearance.

With the corrugation, things are a little more complicated, due to the fact that you must first stretch the cable inside the tube, after which you already fix the track on a brick wall, wood paneling or plaster.

Buy a corrugation with an internal section of twice as much as the diameter of the conductor so that you can easily drag the cable through all the material. Another important nuance - at a negative temperature, the corrugation immediately breaks down, so we do not recommend the installation of open wiring in such weather.

For fixing the cable, it is best to use special clips( they can be seen in the photo above), which are fixed by one self-tapping screw. You can also use metal staples, but their installation is more problematic, besides, it is possible to damage the insulation of the veins. Do not forget, and in the case of a skirting board and in the case of a corrugated pipe after wiring work, call the finished line with a multimeter to make sure it is working.

That's the whole technology of installing open electrical wiring with your own hands. We recommend that you review the video instructions provided to visually see all the nuances of electrical work!
