Possible Causes

Tripped or faulty breaker feeding Nissan EVSE, Loose line connections at breaker or EVSE terminals, Blown internal line fuse, Failed internal power supply module

How to Fix / Troubleshooting

Safety first: Treat all wiring as live until proven otherwise. Use a qualified electrician if you are not experienced with mains work.

  • Check breaker: Locate the dedicated breaker for the Nissan charger. Reset it fully OFF then ON. If it trips immediately, stop and call an electrician.
  • Verify outlet (plug-in models): Test the receptacle with another high-load device or a multimeter to confirm voltage is present.
  • Inspect EVSE wiring (hardwired): With breaker OFF, remove the EVSE cover and check that line conductors are securely attached and not burned.
  • Internal fuse: Some Nissan EVSE units include an internal replaceable fuse. Test and replace only with the exact specified type if blown.

If power is present at the input but the unit remains dead, the internal power supply or control board has likely failed and requires professional replacement.
