I would start by accessing the back of the shore power recepticle. Visibly inspect the recepticle for damage. ( Unplug the cord and check the outside as well). If no visible damage, check the voltage at the back of the recepticle. If all is in order, check the voltage at the main breaker, and buss bar. This will either eliminate, or identify these items as the problem. If no problem is found at this point, the breaker is probably bad. Check the output. Also try switching it off and check to see if it does in fact disconnect. It is uncommon, but not impossible that there is a fuse of some sort inline, but The above check should determine if the failure is between the breaker and the recepticle.
FWIW, I have had 2 of the 30amp recepticles fail over the years due to a reverse polarity issue in the dock. They melted away the potting between the terminals, and I did not discover them intill the power started to fluxuate.
