Possible Causes
Shorted output wiring between Zappi and socket, Internal contactor short, Damaged Type 2 socket with internal short, Incorrectly wired supply polarity
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker; this indicates a fault.
- 1. Visual inspection: With power off, inspect the output wiring and Type 2 socket for signs of damage, burning, or foreign objects.
- 2. Insulation test: Have an electrician perform an insulation resistance test on the output circuit and cable.
- 3. Disconnect cable/socket: Temporarily disconnect the tethered cable or socket from the Zappi output (with power off) and then power on. If the breaker no longer trips, the cable/socket is faulty.
- 4. Check internal contactor: Inspect the contactor for welded contacts or internal shorts. Replace if suspect.
- 5. Verify wiring: Confirm that line and neutral are correctly wired and not reversed or shorted.
