Possible Causes
Open or high‑resistance ground connection, Neutral‑ground bond issues in supply, Leakage current due to insulation breakdown, Faulty GFCI not tripping
How to Fix / Troubleshooting
Safety: Immediately stop using the charger. Turn OFF the breaker and do not restore power until the issue is resolved.
- Verify ground integrity: Have a qualified electrician test the ground conductor from the panel to the Grizzl‑E and correct any open or high‑resistance connections.
- Check for neutral‑ground faults: Ensure there are no improper neutral‑to‑ground connections on the branch circuit.
- Inspect charger internals: With power OFF, look for damaged insulation or conductors touching the metal enclosure.
- Test GFCI function: If the Grizzl‑E has a test function, have a qualified person verify that the internal GFCI trips correctly. Replace the main control board if GFCI is non‑functional.
