UAHaerospace,
Thank you for your informative posts above which really add to the discussion here. It was useful to point out that the 50 amp RV service connection is actually TWO 50 amp legs (phases) of 120 volt supply yielding a total of 100 amps of availability.
This point is really driven home if you simply look at the typical park service panel as shown below.
- The 30 amp outlet has a single 30 amp breaker
- The 50 amp outlet has TWO 50 amp breakers coupled together
- The white GFI AC dual outlet has a single 20 amp breaker
