Had a friend get his trailer fried because the local handy man transferred the wires from the fifty to the thirty because the thirty was having problems and he didn't know what he was doing. Instead of grabbing the hot, neutral, and ground, the idiot grabbed the two hots and a ground pumping 220 into the 110 trailer system. Can we say smoke signals anyone?

Be cautious about looking for 220, (actually the proper voltage would be 240 volts), because there are a few parks out there that you will see 208 volts across the two hot legs, instead of 240 volts, because the transformer supplying power is a wye connected transformer instead of a delta connected transformer. You need to only verify that you have 120 volts to ground or neutral from each hotleg. This is the label at the shore cable connector on our rig.
