Is laying an input cable legal on a wall (temporary shelter)?
After the apartment was flooded, a wire was handed out from the shield to the switch. Without this wire there will be no light. An electrician from the housing office offers to hide this wire in a box and leave it that way. Just too lazy to look for damage. Tell me is it safe? It is legal? Thank.
Hello! I correctly understood your question: have you replaced the input cable from the access panel to the input machine in the apartment panel, laying it on the wall?
If so, then this is normal. It is important that the wire was of normal cross section and new, BUT not second-hand from some segments and thin. In many old houses, the entrance to the apartment was on the wall, and not in it. To make you feel calmer you can hide it in a metal corrugation or pipe, but this is not necessary. Which box does an electrician offer? Metal or simple cable channel?
If the cable burns out, even if he finds where - you need to open the walls and repair it.
Moreover, if you look from the point of view of documents, that is, such as SP 31-110-2003 “Design and installation of electrical installations of residential and public buildings”, where in paragraph 14.11 it is said:
"14.11 In the stairwells, open laying of cables and wires is not permitted. It is permitted to lay power lines for lighting stairwells and corridors, as well as power lines for apartments in buildings up to 5 floors high in steel pipes and ducts. ”
But note that here, in paragraph 14.10, it is said:
"... The risers of the supply lines of apartments, group lines of staircase lighting in residential buildings should, as a rule, be laid hidden in the channels of building structures (electrical units), as well as in floor-mounted distribution devices of lean type ..." That is, according to this document, open wiring should not be, it should be laid in the walls. Pristine type switchgear - refers to switchboards or other switchgear that are hung or otherwise mounted on the wall, not inside it.
It turns out that the laying of the input cable in a metal box can be justified to you in terms of paragraph 14.10.
