Possible Causes
Charger current setting higher than breaker rating, Loose or undersized supply conductors, Weak or defective breaker, Internal short or high inrush current from contactor
How to Fix / Troubleshooting
Safety: Do not repeatedly reset a tripping breaker without finding the cause.
- Verify breaker size: Confirm the breaker amperage matches the Grizzl‑E configuration (e.g., 40 A breaker for 32 A output).
- Check DIP switches: Inside the Grizzl‑E, ensure the maximum current setting does not exceed the breaker rating.
- Inspect wiring: With power OFF, verify conductor gauge meets installation requirements and that all lugs are tight.
- Test breaker: If wiring and settings are correct, the breaker itself may be weak and should be tested or replaced by an electrician.
- Internal fault: Persistent tripping with correct wiring and a new breaker suggests an internal short; inspect contactor and control board for damage and replace as needed.
