Possible Causes
Combined leakage from charger and other loads exceeding RCD threshold, Incompatible RCD type (e.g. Type AC instead of A/F/B), Faulty internal RCD coordination, Wiring errors causing neutral sharing
How to Fix / Troubleshooting
Safety: Do not bypass or oversize protective devices to stop tripping.
- 1. Verify RCD type: Check that the upstream RCD/RCBO is of a type compatible with EV chargers (typically Type A or better, per Easee recommendations).
- 2. Isolate other loads: Temporarily disconnect other circuits on the same RCD to see if combined leakage is causing trips.
- 3. Check neutral wiring: Ensure the charger’s neutral is not shared with other circuits downstream of the RCD.
- 4. Inspect for leakage sources: Look for moisture or damaged insulation around the charger and cable.
- 5. Consult electrician: An electrician may need to reconfigure the distribution board or install a dedicated RCD for the charger.
