Possible Causes
Charger connected to GFCI/AFCI breaker not recommended by manufacturer, Normal inrush current misinterpreted by breaker, Slight leakage current within allowed EVSE limits, Shared neutral wiring issues
How to Fix / Troubleshooting
Safety first: Never bypass ground fault protection where required by code. Consult an electrician for breaker selection.
- Check breaker type: Verify that the breaker type matches Splitvolt installation recommendations. Some EVSEs require standard 2-pole breakers rather than GFCI/AFCI combos.
- Inspect wiring for shared neutrals: Multi-wire branch circuits must be wired correctly with common-trip breakers. Have an electrician verify.
- Try a different circuit: If possible, test the charger on a dedicated non-GFCI 240V circuit (where code allows) to see if nuisance tripping stops.
- If trips persist on correct breaker: The charger may have borderline leakage or arc characteristics; contact Splitvolt for guidance or service.
