You all can argue all you like. In my opinion only a real gambler will run over 50 amps thru the neutral wire. RV's can burn too easily.

Wolfe 10 explained it well and is 100 per cent correct. I hope I never park near some of you.
If a fire, with injuries or death, ever happens because of an improperly wired pedestal, the park owner, electrician and everyone else involved will get burned real bad in court and they should.
While it is highly unlikely, if all the appliances in my bus were on at once, they would use 11000+ watts.

A lot of experts you say? There is a lot of comedy in this thread.
2 x 120VAC on the same phase is safer since the difference between GND and L1 or L2 cannot be pulled higher than 120 VAC!! Too bad logic gets lost in a thread like this. The OP should have been happy to find a post wired the way he did. LOL x 1.
When you tap a 240 VAC single phase line (that most of you think is superior) to get the 2 x 120VAC needed for an RV 50A coach, you run the risk of a floating neutral wire under load being pulled higher than 120VAC between GND and L1 or L2. LOL x 2.
RV 50A is a joke. LOL x 3

Hopefully my sarcasm wasn't lost on you.

Sir, you seem quite knowledgeable. I am curious. Are you a licensed electrician? How many years experience do you have? Are you versed in commercial three phase wiring?

I was trying to follow this thread and I got awfully confused starting somewhere on the second page.
So far what I've gotten is the OP paid for a 50 amp site and when he measured between L1 and L2 he was seeing 0 volts, so if he had a EMS he was no better off than having a 30 amp site. Based on my experience I agree with the OP.
Then I saw the theory about a double pole 50 amp breaker providing 100 amps of usuable service to the mh, after looking "how to wire a 50 amp double pole breaker" I can somewhat see this. I'm still not sure what keeps this setup from throwing a breaker when a mh exceeds 50 amps. I exceed 50 amps at a campground most of the time, and this is the way I suspect most, if not all, 50 amp service at campgrounds ahould be wired.
Then I "think" I'm seeing some talk on using two 50 amp breakers to wire 50 amp service to a mh in order to get 100 amp service, I see a lot of people take issue with this "setup". I also did a search on wiring a 50 amp circuit for something like a residential dryer and can' figure out how it would be physically possible to wire two 50 amp breakers to provide service to a mh. BTW, if I knew I was pulling into a situation like this I would pass this opportunity up.
I guess I need someone to clean this "thread" up so I can understand it a little better.

Sonny,
Not really that complicated. Open the CG pedestal cover. What you will find on any properly wired 50 amp outlet is TWO, repeat TWO 50 amp breakers pinned together (called duplex breakers) feeding the 50 amp outlet. Each 50 amp breaker feeds a different leg in a 50 amp equipped RV. So there is 50 amps on L1 and 50 amps on L2. No different than in a house-- virtually all use two hots.
None of this is new, a theory or speculation.

Brett, that might be part of my problem, I'm thinking about the connection at the campground service pannel not necessairly at the pole. I need to study on that some more.

Same thing at the panel, but MUCH easier for you to just look at the pedestal at your site!
