Distribution Box Incoming Line Procedure
Practice good wiring: secure grounding, neat cable management, proper insulation, and correct wire gauge and breaker size. Include protection devices like breakers, fuses, and surge protectors—each circuit should have its own protection. Electrical power enters a distribution box through the incoming lines using what we call a five-wire system. 1) Generally, the incoming line of power distribution box adopts five wire system, that is, a, B and C three-way phase line (the general color is yellow, green and red), one way zero line (the color is light blue) and one way ground line (the color is yellow with green stripes). Check electrical parameters: First understand the basic electrical parameters of Distribution box so that you can have a general understanding of the capacity and performance of the distribution box.
