Tips: How to Wire DC Circuit Breaker?
- Back-panel wiring. The advantage of connecting cables to the rear of the board is that when maintaining the DC circuit breaker, you only need to disconnect the front power supply instead of rewiring it.
- Plug in wiring. The advantage of plug in wiring is that when the circuit breaker needs to be replaced, you only need to remove the old circuit breaker and replace it with a new one. It is faster and more convenient than before and after the board in operation.
