Here's the reservation system listing for the site we were on at Crooked River State Park near St Mary's, GA last month. The stanchion was a typical 20,30,50 amp park setup.

This shows what happens when the campground site descriptions are made by individuals having no idea of how their equipment works. Probably the same people who design campground showers!

100 amp would be 2x 50 amp (NEMA 14-50 x2)
So, a 100a hookup is 2 standard 50s?

My only disagreement with your reply is that the NEC is not a set of rules. They are standards, minimum standards. I think you missed my point on that but that's okay, we really agree on the need and the NEC is a great set of standards.

Oh yeah! I've worked in the field from 1954 to 1995 when I retired. While the greater part of my experience is in traffic signals, I was a licensed journeyman in the State of Oregon.

We have more in common. I was a traffic signal installer and certified inspector in Florida for 4 years.

I worked in traffic engineering for a few years. Data, patterns, and such.

Don't get me started on traffic signals.. the great guessing game of driving!

You really need to get that 100 amp figure out of your head.

That is what I have read. Going to be a custom RV or park model site that has that much power.

There is no 100 amp hook up. Forget you ever heard it. That comes from newbies and DIY's. 50 amps pedestal outlet is 50 amp @ 240 volts. That's what you need to remember.It goes to your RV and stops at the main breaker. 240 is not accessible there but 50 amps at 120 volts is.

I just talked to the guy at the CG shown above that claims 100a service.

He said some sites have 2 50a sockets for those who need more power. He said they were two dedicated 50a circuits, but they were put in long before he got there. He said he's never had anyone use one, but says bigger buses can. He thought some rigs used a Y connector to join those 2 50a services together.

I told him I and nobody else here knows what a 100a plug looks like. He doesn't either.

So this is weird.

An RV that needs 100a will have 2x 50 amp plugs and 2x 50 amp distribution panels.
Parallel connection is bad juju.
