Method No.

Method No. 2 is called hidden, and involves laying electrical wiring in invisible and inaccessible places. For example, wiring in the ceiling cavities or inside the walls. In accordance with these regulatory acts, wires, cables and electric lines, are laid in a special metal pipe. The pipe itself can be laid in bars, beams, where cuts are specially produced for this. Of course, in the load -bearing elements, laying the electrical wiring can significantly reduce the strength of the structure of the building, therefore, in the case of cable channels laying, the supporting elements try to “get around”.
