shore power 110 or 220
I see the heavy cords and plugs for the class C's so is power at campgrounds 110 or 220?

Circuits that are 120/240 volts are not normally referred to as having phases although the current is flowing 180 degrees apart.

You misunderstood what I was saying. I said if both hot legs were in phase, meaning supplied from the same source hot leg then no neutral canceling would take place. If the 2 hot legs are 180* out of phase then neutral canceling would take place. People keep insisting the 50 amp supply is 2 120v supplies. Technically and by code it's a 240v supply as the 2 hot legs are 180* out of phase. As i said earlier it's no different than the service coming into your house. Almost everything in your house runs off 120v, one of the 2 hot legs. It's quite possible to have no 240v loads at home.
Why people keep insisting that the RV 50 amp supply is some how different is beyond me. It's a 240v 50 amp supply. How the 2 hot legs are used to supply 120v or possibly together to supply 240v is irrelevant. Same thing occurs in your home but it's still a 240v supply.
"Possible" I suppose, particularly for those running gas appliances, but I suspect the vast majority of newer homes these days will in fact run an electric oven and electric clothes dryer, each of which requires 240 vac 2-phase power, which of course is easy since incoming power wired to the house breaker panel is exactly that.
