Possible Causes
Total connected load exceeds generator rating, Short circuit in downstream wiring, Failing main breaker, Large motor loads starting simultaneously
How to Fix / Troubleshooting
Safety first: Turn the generator OFF and restore utility power before working on electrical circuits. Only qualified electricians should open panels.
- Reduce load: Identify and temporarily turn off high‑demand circuits (HVAC, electric water heater, ovens) when running on generator.
- Check for obvious shorts: Look for burned smells or visible damage at the generator output lugs and ATS.
- Test breaker: If the breaker trips at low load, it may be weak and require replacement with a Ryobi‑specified breaker.
- Professional load analysis: Have an electrician calculate total connected load and balance circuits appropriately.
