Possible Causes
Combined GFCI protection in panel and charger, Leakage current near trip threshold, High inrush current on startup, Shared neutral or improper wiring
How to Fix / Troubleshooting
Safety first: Frequent breaker tripping indicates a potential wiring or leakage issue. Do not repeatedly reset without investigation.
- Check breaker type: For EV chargers with built-in GFCI/CCID, the branch circuit should typically use a standard (non-GFCI) breaker unless local code requires otherwise. Consult an electrician.
- Verify dedicated circuit: Ensure the Schumacher charger is on its own dedicated circuit with no other loads.
- Inspect wiring: Have an electrician verify that no neutrals are shared and that hot and neutral/ground are correctly routed through the breaker.
- If tripping continues on a correctly wired circuit: The charger may have excessive leakage or inrush. A technician should test the internal GFCI/CCID module and power module.
