Possible Causes

Shared GFCI protection with other loads, EVSE internal filter capacitors causing leakage, Neutral-ground fault in supply wiring, Defective Nissan EVSE ground fault circuit

How to Fix / Troubleshooting

Safety first: Repeated tripping indicates a protective device is responding. Do not bypass breakers or RCDs.

  • Dedicated circuit: Ensure the Nissan charger is on a dedicated circuit as required by installation instructions.
  • Check wiring: Have an electrician verify that neutral and ground are not bonded downstream of the main panel and that polarity is correct.
  • Inspect EVSE for moisture: Open the unit with power OFF and look for signs of water ingress or corrosion that could cause leakage.
  • Test with another EVSE or EV: Swap components if possible to determine whether the issue follows the charger or the vehicle.

If wiring is correct and tripping persists only with this EVSE, internal leakage or fault protection circuitry may be defective and require replacement.
