30 amp service for 50 amp bus

[belfert]

Typically a pedestal will either have 50, 30 and 15 service or just 30 and 15 service.  You can assume 99.99% of the time that the 30/15 service will be on the same leg.  If they had gone to the bother of running two legs to the pedestal they would have put in a 50 amp plug (and charged accordingly).

What are the chances the campground only ran a 30 amp feed to the pedestal assuming only one outlet or the other would be in use at any one time?

I'd say its almost a certainty that's what has been done Brian. And you can also assume that single hot wire has been sized for as much voltage drop as they thought they could get away with. On the newer pedestals you'll often see a 30 amp and a 15 GFI. You can't run a 30/15 combiner or cheater off a GFI so that option is out if you are on a GFI.

I know people who carry 15 amp receptacles to replace GFCI receptacles during their stay.  They put things bck when they leave.
