Possible Causes
Moisture in socket or cable, Damaged insulation in tethered cable, Incorrect neutral/earth bonding in installation, Faulty internal RCD/RCM module
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset the RCD without investigation.
- Dry and clean: Inspect the socket and plug for moisture. Dry thoroughly before retesting.
- Test with another cable/vehicle: Determine whether the fault follows the cable or vehicle.
- Insulation check: Have an electrician perform insulation resistance tests on the charger’s internal wiring and tethered cable.
- Verify installation: Ensure that neutral and earth are not incorrectly bonded downstream of the main distribution board.
If internal leakage is confirmed, replace the tethered cable or internal RCD/RCM module as appropriate.
