Therefore on a 50 amp service you have 50 amps available on each 120Vac line for a combined 120Vac amperage of 100 amps or 50 amps 240Vac. These lines come in for the pole this way, unless the campground cheats the system and runs 120Vac 50 amps and splits it in pedestal (against code).

The reason you get different readings on each leg is because it depends on how much draw is on each leg of the 50 amp service. For a camper with 2 air conditioners each one will be hooked up to one of the legs, and usually the other systems are tied to only one of the legs which creates an unbalanced load. Hope this made sense.

In regards to the progressive system I am unfamiliar with the system.
Are you sure that the Dryer outlet is the (Same) as a 50 RV ? If so no wonder people are frying their units. I though we had (Elec.codes)! Youroo!!

Ok if that's the case can we not run two "30" amp legs through our cord and put in a 50 amp distribution panel and run each 30 amp leg to each side of breakers.
Much like a house hold panel?

I'm assuming that's what a 50 amp distribution panel does.

One 50 amp 110 down left side
One 50 amp 110 down right side.

Why wouldn't they do that anyway with a 30 amp panel?

Other than politicians, that's where most figuring is done.

Actually the (2) 50 amp and (2) 30 amp plugs are similar but different. They each have an individual NEMA number and purpose.

Because you have 100 total amps (over 3 times as much as a 30 amp), you can run all kind of electrical stuff at the same time now. 2 air-conditioners, water heaters, microwaves, toasters, hair dryers. etc. You are still going to limited to the individual circuit breakers for each outlet. It's so much better than a 30 amp service.
Thanks for the acknowledgment, Lou. Much of my education has been gleaned from yours and everyone else's great posts here in the forums.

It also is easy to understand why some campgrounds charge more for using the 50 amp service, as those campers have the potential to use over 3 times as much electricity as their 30 amp neighbor.

Yep. I got that lecture at the campground I stayed at over the 4th of July weekend. When we were having power issues and the campground "maintenance guy" saw my Franks unit he tried to accuse me of using a "cheater" to get 50 amp service from a 30 amp site using a "Cheater Box."

When I pointed out that to use that kind of box I would need to have a 50 amp cord somewhere (and I did not) and would need a plug into both the 30 and the 20 amp sockets; not just one in the 30 amp socket. He finally backed off. I had to explain what an autotransformer/line conditioner was as he had never actually seen one before. He HAD seen 50 amp units reserving 30 amp sites to avoid paying for a 50 amp site; then using cheater boxes to steal the extra power.
