1, the general switch of the household distribution box can generally choose double-pole 32-63A small air switch or isolation switch. High quality guarantee: the surface-mounted fuse box is mainly made of high-quality nylon + ABS + PC material, which is flame retardant, impact resistant, of high hardness, not easy to break or damage, and ensures long-term use. **Power-off operation** - Before installation, be sure to cut off the total power supply of the household. For the 2025 holiday season, eligible items purchased between November 1 and December 31, 2025 can be returned until January 31, 2026. General small air switch specifications are mainly divided into 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A, 100A, etc. by rated current; In order to ensure safety and reliability, the rated operating current of electrical components should generally be greater than 2 times the required maximum.

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.
