Winco Load Step Trip / Overload Shutdown

Generator shuts down when large motor loads (well pump, AC) start, but restarts and runs with smaller loads.

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

Generator undersized for motor starting current, Weak engine output, Loose connections causing voltage drop, Incorrect breaker size or trip curve

Safety first: Disable AUTO while evaluating loads.

Assess load sizing: Compare motor starting kVA to Winco generator rating. Consider soft starters or staggered start controls for large motors.
Check fuel and maintenance: Ensure engine is producing full power (clean air filter, proper fuel pressure, fresh plugs).
Inspect wiring: Have an electrician check for undersized conductors or loose lugs that increase voltage drop.

If the generator is too small for the load, upgrading capacity or adding load management is required.
