Possible Causes
EVSE leakage current interacting with upstream GFCI, Shared neutral on multi-wire branch circuit, Incorrect breaker type for EVSE load profile
How to Fix / Troubleshooting
Safety first: Only a licensed electrician should modify breakers or branch circuit wiring.
- Check circuit design: Confirm the EVSE is on a dedicated two-pole breaker with no shared neutral, as per ClipperCreek installation instructions.
- Breaker type: Consult the EVSE manual; many EVSEs should not be installed on GFCI breakers because they have internal GFCI. Use a standard two-pole breaker of correct rating unless local code requires otherwise.
- Inspect wiring: Ensure hot conductors and neutral (if present) are correctly routed through the breaker and not shared with other circuits.
Correcting the branch circuit design usually resolves nuisance tripping. Do not bypass required protection; instead, use compatible devices.
