All the same phase and neutral wire loop, should be laid in the same metal trunking, cable tray Shandong same path no anti-interference requirements of the line, can be laid in the same metal trough, the total cross section of the wire or cable trunking (including the outer sheath) should not exceed 20% within the trunking section, carrying conductors should not be more than 30. Control signal lines or the like thereto, the total cross-sectional wire or cable to be more than 50% down the trunking section, the minimum number of cables or wires.

金属线槽应可靠接地或接零,但不应作为设备的接地导体由金属线槽引出的线路,可采用金属管,硬质塑料管、半硬塑料管、金属软管或电缆等布线方式。电线或电缆在引出部分不得遭受损伤。

Metal trough ground or zero should be reliable, but should not be used as equipment grounding conductor lines drawn by the metal trough, can be a metal pipe, rigid plastic pipes, semi-rigid plastic pipes, metal hoses or cables and other wiring.
