Possible Causes
Shorted power contactor, Internal wiring short between line and neutral, Damaged tethered cable causing internal short, Incorrectly rated MCB for charger current
How to Fix / Troubleshooting
Safety: Do not keep resetting a breaker that trips immediately; this indicates a serious fault.
- Step 1 – Visual inspection: With power OFF, inspect the charger casing and cable for burn marks, melted insulation, or impact damage. Do not use the charger if any damage is visible.
- Step 2 – Confirm breaker rating: Check that the MCB/RCBO rating matches the Pod Point model (e.g. 32 A for a 7 kW unit). An undersized breaker will nuisance trip under normal load.
- Step 3 – Try without vehicle: Turn the breaker ON with no vehicle connected. If it trips immediately, the fault is within the charger or supply wiring.
- Step 4 – Electrical tests (electrician only): Isolate supply, open the unit, and perform insulation resistance tests between line, neutral, and earth. Check the contactor and internal wiring for shorts or carbon tracking. Replace any damaged wiring or the contactor as needed.
- Step 5 – Replace damaged cable: If insulation resistance is low on the tethered cable, replace the entire cable assembly; do not attempt to repair the cable sheath only.
