Precautions for Residual Current Sensor wiring

1. Be sure to distinguish phase wire, n wire and pe wire before wiring, otherwise problems will occur, resulting in inaccurate measurement data and false alarms.

2. The phase line and the N line must pass through the residual working current and voltage transformer together. The PE line cannot directly pass through the transformer, which will also affect the deviation of the system circuit design parameters, so be careful.

3. If the N line cannot pass through the transformer together with the phase line, once the three-phase load capacity is unbalanced, a current will flow through the N line, and the detector detects the current control signal, and some misoperation occurs.
