Is it possible to cross wires in the corrugation during wiring?
Hello. During the installation of hidden and open electrical wiring laid in the corrugation or cable channel, is it allowed to intersect some lines with others? For example, if the input line laid to the panel intersects with lines extending from the panel to the sockets and lighting, or when the socket group intersects with the lighting group?
If it is cable lines, then it is allowed. If the wiring is laid with a wire with one layer of insulation, it is necessary to additionally protect each of the crossed wires with several layers of insulation tape.
