I have a 50A inlet in the bow locker on my 52. I runs to a Charles automatic transfer switch in the ER. You most certainly have some kind of auto or manual transfer switch or plugging in one cord would energize the other and sparks and shocks would certainly follow. If one 50a inlet works and assuming you don't have multiple 50a inlet selectors on your AC distribution panel, I would be in search of the transfer switch. Following the cable from the cablemaster tub inside the boat will eventually point the way. If not obvious in the ER maybe look behind the AC panel (turn off shore power first).

My transfer switch has a manual override on it in case the automatic system fails. It may be as simple as that. Either way let us know what you find. Best of luck.
