Hot skin safety test time

[Kurt Horvath]

Ralph,

Does this apply to the coaches that have 50 amp service?
If so, and I plug into a 30 amp. outlet only one leg of the two leg
system is hot, the other side has no power, Do I run the test as
first decribed or is there an alternative proceedure?
I have on rare occasions felt that tingling on the coach.

Thanks,
