50 amp to a 30 and 20 out how to do? HELP!
I'm adding a second ac to my WW trailer, it has a 30 amp service, I am wiring the 2nd ac with seperate wiring and load center and breaker out of the load center will be a plug for the ac. I was looki...

I don't know what the code is for RV site services. A friend of mine ran into this fairly recently after a discussion on electrical services. Just out of curiosity, he checked the service he was plugged into at the time and discovered his two 25A circuits were on the same phase. He had voltage from hot to neutral on both circuits and "0" between the two. Of course you know this must mean they're in phase since any phase difference would show some voltage difference between the two. He didn't look into this any further before they left the next morning, and since it was of no consequence to him at the time anyway. He just thought it odd enough to comment to me during a recent conversation on the same subject.
I don't know how the pedestal in question was wired internally. Nor do I know if others in the same park were like this one. I made an estimate on how it might be wired to get the results of the same phase on both circuits of a 50A service.
Perhaps there have been changes in the code that might allow this, something the park manager did himself without knowing the code, or perhaps an honest error by someone else that should never have been working on a power pedestal. It is only 50A at 120V which really isn't that much for one conductor to the pedestal. I don't know. My friend is a retired Radar Engineer and I trust what he told me to be accurate. He's actually sort of anal that way. He probably took his oscilloscope to the pedestal for a better investigation. lol
