Possible Causes
Tripped or faulty circuit breaker, Open circuit in branch wiring, Loose line connections at Wall Connector terminal block, Internal fuse or power supply failure
How to Fix / Troubleshooting
Safety: Treat all wiring as live until verified otherwise with a meter. Only qualified persons should open panels.
- Check breaker: Verify the dedicated EV charger breaker is in the ON position. If tripped, reset once. If it trips again immediately, do not continue resetting; investigate the cause.
- Test outlet or hardwire feed: For hardwired units, an electrician should measure voltage at the Wall Connector input terminals. For plug‑in units (where applicable), test the receptacle with a known good load.
- Inspect terminations: With power off, check that all line conductors are securely landed in the Wall Connector terminal block and show no signs of overheating.
- If power is present but unit is dead: The internal low‑voltage power supply or control board has likely failed. Replace the Wall Connector.
