Possible Causes
Undersized breaker for charger rating, Shorted power module input, Miswired supply (e.g., neutral issues), Defective main contactor causing high inrush
How to Fix / Troubleshooting
Safety first: Repeated breaker tripping indicates a serious issue. Do not keep resetting without diagnosis.
- Step 1 – Verify breaker size: Confirm the breaker rating matches Electrify America installation requirements for your charger model.
- Step 2 – Visual inspection (power OFF): Open the charger and inspect for obvious shorts, burned components, or loose strands at input terminals.
- Step 3 – Isolation test (technician): A qualified technician should disconnect the power module from the input and see if the breaker still trips when energizing only the control circuit.
- Step 4 – Replace faulty module: If the breaker only trips when the power module is connected, the module may be shorted and must be replaced.
