1) Generally, the incoming line of power distribution box adopts five wire system, i. three phase lines a, B and C (generally yellow, green and red), one zero line (light blue) and one ground line (yellow with green stripes). Choose the right box based on environment (indoor/outdoor), load capacity, and durability. Ensure safe placement: install in dry, accessible areas with good ventilation and at appropriate height (typically ~1. Size determination, installation method and wiring mode of distribution box! The distribution box is the central hub of the home circuit and the general control of our daily power consumption. Lateral taps off of the main trunk are used to cover most of a feeder's service territory.
