To add to Michaels excellent response. If I interpret your first question, can it be used as to plug into shore power. Yes it could but it is not a good move for two reasons. One, it would require a hot Male plug. Two, the buddy plug is in the circuit after the transfer switch, so if you were using it to power the coach and accidentally or intentionally cranked the generator, the generator would come on line out of phase with the grid. Grid wins, generator loses.
