Jim, there is a big watchout with the ACs when hooked up to a cheated power pole. Since all of the 120 is on the same phase, all four ACs running simultaneously is going to pull about 60 amps and a breaker is going to pop at best, or wiring overheat at worst. The underlying danger is with that AC's running, the voltage drops and this can harm the compressors. Fortunately Chester has a voltage protection system which should automatically disconnect him if this happens.

True 50 amp is actually 50 amp on EACH leg, for a total of 100 amps. The cheated wiring that Chester is plugged into is 50 amp total.

Who knows what wiring gauge the park used if they wired the pedestal in the cheated way.

So why would they do this? Money. Let me give you an example. I recently ran power to the RV parking pad behind the house. A run of about 200 ft from the house to the pad. I needed outdoor burial cable. The cost to run # 10 wire rated for a 30 amp circuit was about $160, the cost to run #6 wire good for the 50 amp service was $600. Heavier wire and one additional conductor explain the cost differential.
