Wiring in a wooden house

Wiring - an important part of electrical log home. On how she correctly designed, installed and operated, independent degree of electro - fire safety and housing. Electrical wiring must meet the requirements of building regulations for electrical wiring in a wooden house on fire safety.

Mainly used type 2 assembly entries: hidden and external. Here is an example of photographs of foreign postings and you will understand why in this article we will not talk about it. Note that, as fits the interior lining of external wiring.

Installation of electrical wiring in wooden buildings is performed by special rules PUE ("Rules Installations") have been developed due to the fact that the tree of which the walls in these buildings is a source of increased fire safety and a discrepancy of installation wiring PUE is the cause of most occupied.Electric entering the house with walls made of burnt material (wood), is only possible with copper wire that runs through the tube of metal, mounted in the wall. Use of aluminum wire prohibited.You must use only cable with combustible insulation (NYM or VVHnh). If the cable is not nezhoryayemoyi isolation, it must be placed in the duct, electrical baseboard or wall corrugated pipe. One can conclude that the wire has no insulation directly on the wall, but in this case the distance between its surface and the leadership should be less than one centimeter, which can be used "videos"-isolators.Seeing the light, coming in cavities between base and ceiling, can be placed in a corrugated tube. Transitions between the walls of the wires should be made only in metal pipes.

According to the requirements wiring in wooden houses should be placed into the shell and prevents its burning. Usually used steel pipe, nonflammable hofroshlanh, a special box with PVC does not support combustion. If it is a steel pipe, it is on the inside should be galvanized or painted.

It is advisable to install wiring for metallohofr not strictly horizontal, but with some bias, which provides a flow of condensate. In the formation of inside wall dew point condensation will inevitably arise.

Requirements for electrical wooden house set in GOST R 50571.15-97 (IEC 364-5-52-93) "electrical buildings. Part 5. Selection and installation of equipment. Chapter 52. Electric wiring"

Wiring in a wooden house can be made in special plastic boxes. However, it spoils the aesthetics of the interior. Amid square log stack boxes are clearly visible. Boxes are painted in color of wood factory production - a very expensive price.

In our opinion, any variant of external wiring - undesirable for a wooden house!

Let us to consider the hidden wiring that does not spoil the appearance of the wall and does not affect the interior of the house. Stipulate immediately that this method requires the work of laying wiring at installation stage house walls and floors.

This means that all design work must be done at the stage of designing a model home. Our company practices of technological holes for concealed wiring inside the walls of the timber manufacturing process. Use with new machine tools with CNC allows you to make this work with high accuracy.

Here is an example of laying wiring hidden in a wooden building and installing electric fornitury:

Conclusions:

1. Proektiruyte electrical circuit wiring together with the architectural project - then do not have to remodel and lay a box of insulators for beautiful walls.

2. Use hidden wiring - the interior remains beautiful.

3. Prefer for the construction of a metal grounded hofrotrube - enhance safety.

4. Place the outlet near the floor - the quantity of timber technology drilled holes.

5. Do everything you can to your electrician friends with builders on the stage walls.

6. Let complex work professionals
