Crack Down on 50 Amp Rigs Using 30 Amp Sites
I don't know how long this has been going on but I learned today that some RV parks including the Washington/Pittsbugh KOA I had booked has a policy that if your rig has 50 amp service, you can't use ...

I have been following this thread since the beginning, and I have yet to see anybody explain exactly how a 50 amp rig can draw more than 30 amps from a 30 amp socket/breaker! Perhaps I missed it...
I have, though, seen many say that two air conditioners can not be run on 30 amps, yet my 30 amp 2 A/C rig runs both of them no problem. Yes, I can even run the microwave with both A/C units operating!
That's because drawing more than 30amps isn't the issue.
30amp outlet is just a rating but 30amp rigs rarely reach 30amps draw (typically for a couple seconds when the compressor kick on).
If you have soft start on the compressors, you can run them but you are fire hazard. If you are running 2 air/con plus the microwave, you are probably right at 30amps continuous load. The cord and outlets are only rated at 24amps continuous. Then the design of electrical systems (per code) does not assume that kind of loading, so if you get multiple rigs pushing the limits of a 30amp pedestal, you exceed the branch capability.
