30 amp does not want to stay in the on position :H
That is the MAIN AC Circuit Breaker
With it tripping NO AC Power from gen or shore power
YOU have a short/loose wiring most likely in the 'ATS' (Auto Transfer Switch)
IT is the 'box' where shore power cord and gen power cord goes into and then wiring goes out to main panel
IF yo don't have an ATS and have to plug gen in then problem is in that outlet or wiring going to main panel
A 30A (or other) breaker not staying in the on position is indeed indicative of a short/overload or (much more rarely) of a bad/worn out breaker.
If this is the 30A main breaker in the RV's distribution panel, the problem is not with the ATS as the breaker is after the ATS, and likely something in the main panel itself (since otherwise one of the branch circuit breakers would be tripping). Another possibility is that you have some combination of loads that exceeds 30A, but where each load does not individually exceed the branch circuit ratings--such as the microwave, the air conditioner, and maybe the converter and water heater all trying to run at once.
If it's the breaker on the generator, it could be the ATS or the wiring between the generator and the transfer switch.
Obviously, if you don't have an ATS, it's not the problem.
