The residual current circuit breaker is an indispensable part of the split meter ready board. Now let's take a look at what should be paid attention to when installing the residual current circuit breaker of the split meter ready board.

 

1. If the power supply side and load side are marked on the wiring terminal of the split meter ready board, the wiring must be in accordance with the regulations and cannot be reversed

 

2. The residual current circuit breaker can only be used in the system where the power supply neutral line is grounded. It does not protect the system where the transformer neutral line is insulated from the ground. When wiring, the neutral line at the output end of the residual current circuit breaker cannot be repeatedly grounded, otherwise the residual current circuit breaker will malfunction

 

3. The single pole two wire and three pole four wire residual current circuit breaker products are marked with N pole and L pole. When wiring, the neutral line of the power supply should be connected to the N pole of the residual current circuit breaker and the live wire should be connected to the L pole

 

4. When the residual current circuit breaker is powered on for the first time, the "test button" on the residual current circuit breaker shall be operated to simulate whether it can operate normally in case of leakage, and it can be put into use after confirming that the action is normal

 

In addition, during the use of the residual current circuit breaker in the split meter ready board, the test button shall be operated regularly to check whether the protective function of the residual current circuit breaker is normal.
