(1) Metal wire duct wiring is generally suitable for indoor dry in normal environment and exposed in places that are not susceptible to mechanical damage, but it should not be used in places where the metal wire duct is heavily corroded.

(2) Lines should be smooth, without distortion, and the inner wall should be smooth and free of burrs.

(3) When the metal wire channel is installed vertically or at an angle, measures should be taken to prevent the wires or cables from moving in the wire channel.

(4) All phase wires and neutral wires of the same loop should be laid in the same metal trunking.

(5) The metal trunking should be reliably grounded or connected to zero, but should not be used as the grounding conductor of the equipment.

(6) The wiring drawn from the metal trunking can use metal pipes, rigid plastic pipes, semi-rigid plastic pipes, metal hoses or cables. The wire or cable must not be damaged in the lead-out.

(7) The hoisting metal wire channel is mainly used for indoor lamp installation.
