Possible Causes
Charger installed on GFCI/AFCI breaker not recommended by FLO, Leakage current near breaker threshold, Electrical noise from charger switching circuits, Shared neutral or wiring issues in panel
How to Fix / Troubleshooting
Safety first: Ground-fault protection is critical; do not remove required protection without consulting an electrician and FLO guidelines.
- Check installation manual: Verify whether FLO specifies a standard breaker or a particular type of GFCI/AFCI for the charger.
- Dedicated circuit: Ensure the charger is on a dedicated circuit with no shared loads or neutrals.
- Panel inspection: Have an electrician inspect the panel for shared neutrals, loose connections, or miswired breakers.
- Breaker replacement: If allowed by code and FLO, replace a combination AFCI/GFCI breaker with the recommended type (e.g., standard breaker with internal GFCI in the charger).
- If trips continue: A technician should measure leakage and noise currents from the charger and, if excessive, replace the main control board or power board.
