Possible Causes
Shorted load circuit, defective appliance, undersized wiring, internal alternator fault
How to Fix / Troubleshooting
Safety first: Open the generator main breaker and the main utility breaker before working on circuits. Only qualified electricians should open panels.
- Isolate circuits: Turn off branch breakers in the home, reset the generator breaker, then turn on circuits one at a time to identify which circuit trips the breaker.
- Inspect suspect circuit: Check outlets, cords, and appliances on the problem circuit for damage or moisture.
- Check wiring size: Ensure conductors between generator and ATS are sized per Champion and code requirements.
- Test alternator (technician): If the breaker trips with no load connected, the alternator or internal wiring may be shorted.
Do not replace breakers with higher ratings to stop nuisance trips; this is unsafe.
