EVSE trips the upstream circuit breaker immediately or within a few seconds of starting a charge.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a breaker that trips instantly; this indicates a serious fault. Turn OFF and lock out the breaker.
- Inspect wiring (power OFF): Open the EVSE and check for pinched wires, exposed conductors, or screws driven into wiring.
- Check contactor coil: Disconnect the coil leads and try powering the EVSE (without allowing charging). If the breaker no longer trips, the coil may be shorted.
- Measure insulation (advanced): A megohmmeter can be used by a qualified technician to test insulation resistance between line and ground.
Replace any shorted components (contactor, control board, wiring) before restoring power. If miswiring is found, correct per ClipperCreek diagrams.
