60 Amp Fairground Outlet
Posted 11 December 2012 - 11:02 AM
Is this correct, and if I make an adapter from 50 to 60 amps will I be able to use it without problems?

Would sure check it out with a voltmeter before plugging in.
If it looks like a 50 amp outlet:
Outer prongs are both HOT
Inner straight prong is NEUTRAL
Inner round is GROUND
Either outer to center straight or round= 120 VAC
Outer to outer= 240 VAC
Center straight to center round= 0 VAC
If it looks like a 30 amp outlet, RUN, FOREST, RUN.
If it is a 3 phase plug, RUN, FOREST, RUN.

Heres what I would do. I have 50 amp power cable for my coach and therefore I would plug into the 50 amp plug. I would then go to the GCs office and ask, "What is the 60 amp plug for?".

Thanks for your response. The only apparent difference was that the bottom pin was horizontal instead of vertical. There was, in fact, 120 vac on both outside legs. What about the phase - could it be different?

This does not look like they should be used in RV Camp grounds, Lack of ground wire if someone who did not know what the wiring should be,(Not a Master Electrician) installed them.
Being a Fairgrounds these are for High Power 3 phase Motors used on rides !!!!
