15-way waterproof plastic electrical distribution box

Each household has an electrical distribution box, which is the controller of the domestic circuit.

Key points to choose the one for your home:

1. The main switch of the household electrical distribution box generally adopts a 2-pole circuit breaker or an isolation switch (single-phase power supply system), and the rated current of the circuit breaker should be determined according to the total power consumption of the household.

If the total power is less than 6KW, a 32~40A circuit breaker is recommended, and if the total power is 6KW-8KW, a 40-63A circuit breaker is recommended.

2. It is recommended to use 1P+N (phase + neutral wire) products for branch circuits. When the line fails, the phase and neutral wires of the power supply can be cut at the same time to ensure the safety of personnel and electrical equipment.

3. The lighting circuit should take into account the total current of the household lighting fixtures. It is recommended to choose a circuit breaker with a rated current of 10-20A.

4. The socket circuit can choose 1P+N, 30mA leakage protection products, and the rated current can choose 16A-25A.

5. 5. The rated current of the air conditioning circuit is based on the performance of the air conditioner. Generally, 16-20A is recommended. The cabinet type air conditioner can choose 1P+N, 30mA leakage protection circuit breaker, and the rated current is recommended to choose 16A-25A.

6. Other heavy-duty electrical appliances, such as electric water heaters, should be individually equipped with protective circuits.
