Charger causes nuisance tripping of a GFCI or AFCI breaker upstream, even though the charger itself shows no error.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Do not modify breakers or wiring yourself unless you are a qualified electrician.
Steps to try:
- Check installation manual: Verify whether Cadillac specifies a standard (non‑GFCI) breaker for the EVSE circuit, since the charger has built-in ground fault protection.
- Isolate the circuit: Ensure the EVSE is on a dedicated circuit with no other loads.
When to call a technician: An electrician should verify wiring, neutral/ground separation, and breaker type, and replace the breaker with the recommended type if necessary.
