Assuming these are breakers for the 120V AC system, you plainly have some sort of a short circuit there, such as a miswired transfer switch or (if you have to plug the shore power cord into a generator socket) a miswired generator socket, and perhaps some other AC wiring problems as well.
Frankly, I don't think this is something that is practical to troubleshoot and diagnose safely over an internet discussion forum. I very strongly suggest you find an electrician or at least someone who is very well versed in AC wiring to help you out. It would be well to double-check that the AC ground wiring is intact and not somehow improperly interconnected with the hot or neutral lines.
