How does 50 amp work?
Can someone explain how the 50 approach system works? Normally 50 amp is 220 but the rv is not 220 its 110 riright? So how does this work?

The 220VAC is two phase power with each leg 180 degrees from each other.
Excellent visual for the lay person(even if there are some technicalities).
If you tie Phase 1 back to the common, you get 120v.
If you tie Phase 2 back to the common, you get 120v.
If you tie Phase 1 to Phase 2, you get 240v.
Generally in an RV, Phase 1 & 2 are only tied back to the common, so you wind up with 50amps @ 120v on each Phase (aka: Leg).
