Possible Causes
EVSE installed on a GFCI/AFCI-protected circuit contrary to instructions, Cumulative leakage from EVSE and vehicle exceeding breaker threshold, Electrical noise from EVSE switching circuits, Shared neutral or wiring errors
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping GFCI/AFCI without investigation. Turn OFF power and consult the installation manual.
Steps:
- 1. Verify circuit type: Check Leviton’s installation instructions; many EVSE units require a dedicated, non-GFCI breaker because they have internal GFCI protection.
- 2. Inspect wiring: Ensure the EVSE is on a dedicated two-pole breaker with no shared neutral or multi-wire branch circuit miswiring.
- 3. Remove unnecessary GFCI/AFCI: Have an electrician replace an incompatible breaker with the recommended type if allowed by code and manufacturer.
- 4. Test with another EV: If tripping only occurs with one vehicle, its onboard charger may have high leakage current.
