Generator circuit breaker trips when AC kicks on

Do this the right way. Apparently changing parts (the thermostat) is not getting the desire results.

Use an amp meter and see what the actual load is. If below the rated capacity of the breaker (more than likely) then change the breaker. The can and do get weak and fail when they afe.

If amp load is above the rated capacity of the breaker, look for a failing compressor in you air conditioner. Air filters clean? Evaporator and condenser coils clean? Fan() working?
