I'm not the electrician here. But this thread started out by numerous posts saying 50 amp was (50A X 120V = 6000W) X 2 = 12,000W. And now you're saying we have a 20A/30A breaker. That would be (20A X 120V = 2400W)+ (30A X 120V = 3600W) = 6,000W. If that is the case, then what is the campground providing at the pedestal, 30A in each hot leg or 50A?

So when you use a 50-30A adapter, does it split it up 15A to each hot leg of my power chord or does it just send 30A down one leg of the power chord and then it gets split up somehow at my breaker?

I'm not at my RV now so can't discuss what breaker I have. My point was that all of my RV's appliances are only 120V.
