By the way donandpatti , what problem are you having that you think a transformer will fix?

If they tied an old 30 amp line to only one 50 amp breaker, and then from that one 50 amp breaker fed both contacts of a 50 amp outlet one could see the readings oldbird listed above. This could be tested by turning off one 50 amp pedestal breaker at a time. Turning one off would make no difference and turning the other off would shut down all power.

The problem is, oldbird said it happens at multiple parks and has happened with several different coaches. This suggests the problem isn't in the coach or the park wiring.

Oldbird, can you confirm there are two 50 amp breakers in the pedestal? Can you check for 120vac from each line to neutral and 240vac line to line?
