I went to the KOA site referenced in the first post here and followed him OK until he said that 50 amp was 12000 watts, 50 amps X 240 volts = 12000 watts.

What I have in my Montanna is 50 amps X 120 volts = 6000 watts. I have 2 hot legs of 120V @ 50 amps each so, yes I have 50 amps X 120 volts = 6000 watts X 2 = 12000 watts. But each receptacle and appliance in my RV is only connected to one hot leg or 120V. There are no receptacles or appliances connected to both hot legs as in a 240 V application.

I think this site explained it well:

Your dealer is correct and your description is accurate. Nothing is 240V in our rigs, but there are two 120V 50A busses; 6KW each.
