How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping RCD or breaker. Turn off power and leave it off until the fault is found.

- Inspect cable: Look for cuts, crushed sections, or animal damage along the entire length.
- Verify wiring: Have a qualified electrician confirm that neutral and earth are correctly separated and that the charger is wired per Hyundai’s diagram.
- Insulation testing: A technician should perform an insulation resistance test on the output circuit and cable.
- Replace damaged components: Any cable or board showing low insulation resistance or visible damage must be replaced.
