A/C Tripping breaker
What could cause the A/C to trip the breaker after it's been running for a while? Sometimes it trips it's own 20amp and sometimes it'll trip it's 20amp along with the main 30amp. It'll only do it when...

At a minimum we need to know the voltage before it trips out while RUNNING... which means it's not a start capacitor problem. If you have another 20A breaker I'd swap them out. With high use breakers do loose some of their amp rating.
If the voltage while running gets below 108V the amps go up and that could be the reason the breaker is popping BUT it does it on generator so the voltage should be above 108.:h
A leaky cap may get worse as it warms up - I've seen this many times repairing electronics. The cap is always in the circuit being charged so just because it doesn't trip the breaker on start up doesn't mean it isn't the cause of the eventual overload. Caps don't always just fail all at once. They can function even while slowly dying.
