Possible Causes

Incorrect RCD type (e.g., Type AC instead of Type A/B), Cumulative leakage from multiple devices on same RCD, Internal leakage in go-e Charger due to moisture, Faulty vehicle causing excessive leakage

How to Fix / Troubleshooting

Warning: Repeated RCD tripping indicates potential leakage; do not bypass protection.

  • Verify RCD type: Check that the installed RCD matches go-e requirements (usually Type A with integrated DC detection in the charger, or Type B). Replace incorrect devices.
  • Dedicated circuit: Ensure the charger is on a dedicated circuit and RCD, not shared with many other loads that add leakage.
  • Inspect for moisture: Open the charger (power off) and look for water ingress or condensation. Dry thoroughly and correct sealing issues.
  • Test with another EV: If possible, charge a different vehicle. If only one EV causes trips, its onboard charger may be leaking and needs automotive service.
