Possible Causes

Cumulative earth leakage from charger and other appliances, Incorrect type of upstream RCD for EV use, Short circuit or insulation fault in output cable, Internal RCD/RCM malfunction causing upstream trip

How to Fix / Troubleshooting

Safety warning: Repeated breaker trips indicate a potential safety issue. Do not repeatedly reset without investigation.

  • 1. Isolate other loads: Turn off or unplug other large appliances on the same RCD to see if the EV charger can operate without tripping.
  • 2. Verify RCD type: Ensure the upstream RCD/RCBO is of a type suitable for EV chargers (often Type A or B as specified by Land Rover). Consult an electrician if unsure.
  • 3. Inspect cable and plug: Check the Land Rover charger cable for damage or signs of arcing at the plug or vehicle inlet.
  • 4. Test insulation (qualified only): An electrician can perform insulation resistance tests on the charger output and supply wiring.
  • 5. If trips persist with correct RCD and good wiring: The internal RCD/RCM or control board may be faulty and require replacement by a service technician.
