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. Ensure safe placement: install in dry, accessible areas with good ventilation and at appropriate height (typically ~1. The distinction between 1P and 2P circuit breakers plays a pivotal role in determining the appropriate protection level for various circuits. Connection method: Each switch takes a wire from the incoming point and connects it to the incoming end of the switch, or uses parallel connection to reduce the difficulty of wiring. (1) Wiring method of distribution box 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.
