Hot skin safety test time

[Scott Forman]

Ralph, thanks for this, I have "hot skin" and also had it on my old
FC. I have a question...

One question...my coach is plugged into a non-grounded (the old 2-pin
type) outlet when parked at home. I am no electrician, but I had
convinced myself that this non-grounded outlet was the source of
my "hot skin". The "hot skin" isn't there when on generator power.
Is there any logic to that theory?
