Possible Causes

Heating of internal insulation causing leakage, Degraded cable insulation under load, Overly sensitive or incompatible upstream RCD type, Vehicle onboard charger leakage current near limit

How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a tripping RCD without investigation.

  • 1. Reduce current:
    • Lower the charging current in the app and see if the RCD still trips.
  • 2. Check cable temperature:
    • After a period of charging, carefully feel the cable and plugs; they should be warm at most, not hot.
  • 3. Try another circuit with appropriate RCD:
    • Use a circuit with an EV-compatible RCD (Type A with DC detection or Type B as required).
  • 4. Test with another EVSE or EV:
    • Determine whether the leakage is associated with the charger or the vehicle.
  • 5. If the charger is identified as the source:
    • Internal insulation or filter components may be degraded.
    • Contact NRGkick support for detailed leakage testing and repair.
