How to Fix / Troubleshooting
Safety first: Repeated RCD tripping indicates a potential safety issue; proceed cautiously.
- Visual inspection: Check the Type 2 socket and cable for moisture, dirt, or damage. Dry thoroughly if wet.
- Dedicated circuit: Ensure the charger is on its own RCD/RCBO as per NewMotion and local code recommendations.
- Test another vehicle/cable: Try a different EV and/or cable to see if the tripping persists.
- Check leakage type: Confirm that the upstream RCD type (e.g., A, B, F) is compatible with EV chargers and DC leakage behavior.
- Consult electrician: Have a qualified electrician measure leakage currents and, if necessary, reconfigure the distribution board to avoid stacking RCDs.
