Type-B RCD 1P+N (Tongou TORD4B-63)

In January 2019 the UK introduced 18th Edition wiring regulations (722.531.2.101) for EVSE installations that requires the use of either a Type B RCD (with built-in DC capability/detection) or “RCD Type A and appropriate equipment that provides disconnection of the power supply in case of DC fault current above 6mA”.

Since the EmonEVSE / OpenEVSE does not have DC detection this Type-B RCD is required for installation in the UK. This RCD should be used in conjunction with a 40A MCB to provide overcurrent protection.
