Is it possible to lay the cable in transit through the premises?
Hello. Is it allowed to transit cable over wooden ceilings and brick walls in corrugated pipes on clips through unheated utility rooms with concrete floors, including the grain room where grain is crushed?

It is possible to lay wiring in transit, but in this case, to ensure fire safety, it is necessary to choose a corrugated pipe made of self-extinguishing material that does not support combustion. The cable must be correctly selected for the current, so that it does not undergo overheating. The type of cable is suitable - VVGng or another, which does not support combustion. And it is also necessary to exclude mechanical impact on the cable, as the plastic corrugation does not protect the cable from damage.
