Possible Causes
Loose high-current connections, Undersized branch circuit wiring, Blocked ventilation, Degraded contactor contacts causing high resistance
How to Fix / Troubleshooting
Safety first: Turn OFF the breaker and allow the unit to cool before opening. High temperatures can cause burns.
- Check installation: Ensure the EVSE has the required clearances and is not installed in a confined, unventilated space.
- Inspect connections (power OFF): Tighten all line, load, and contactor terminals to specified torque. Look for discoloration or melted insulation.
- Measure current draw: Have an electrician measure charging current and compare to EVSE rating. Overcurrent can cause overheating.
- Contact replacement: If the contactor shows signs of overheating, replace it to restore low-resistance switching.
Do not ignore persistent overheating; it can lead to component failure or fire risk.
