Both Zaptec Go and Zaptec Go 2 include built-in 6mA DC earth fault protection (RDC-DD, IEC 62955). This is electronic and auto-resets when you replug the Type 2 cable.
To complete your installation and meet safety requirements, you also need to install a separate 30mA Type A RCD (for AC earth faults) and an upstream circuit breaker at each charging station, as required by local regulations.
