A/C breaker trips

[Pete Masterson]

If the breaker trips just after (or as) the compressor cycles on, then it's likely that the breaker has gotten weak (or is the wrong type). I can watch the amp gauges as the AC compressors cycle and I can see the needle jump into the red zone for a fraction of a second -- if the breakers on the circuit didn't have the built-in trip delay, they'd pop every time. 

It is also possible that there's something wrong with the AC compressor motor, but that's usually accompanied by odors, (oily smell, ozone, or burning insulation) that tip you off. 

Initially, when the compressor first starts after the AC has been off for awhile, there's little resistance to the start. Once the compressor has run, there's some built up pressure that bleeds off over time... still there's more resistance to the compressor motor when it cycles on once the system has been pressurized (running) for a time.

Thanks for the assist.

My primary shorepower problem is lack of a good household circuit.  I

need to get an electrician to create a new 220 V, 50 amp RV shorepower

outlet. 

The genset (and breaker) are a few years old,

but just today run for the first time.  The breaker does not trip when

the unit is first turned on, only after it has run a bit.  It may be a

bad breaker, but I am thinking probably something else.  Any other ideas?
