Hot skin safety test time

[Ralph L. Fullenwider]

Yes there is logic to that because the ground and neutral tie is not
present so there is only a path back to neutral and not ground, but still
go through the switching each breaker off and check. You will or should not
have a hot skin when plugged into campground shore power, or gen set, and
the hot skin is more prevalent when plugged into a 110 vac source vs 220 vac.

In recent posts, we learned that the only place that the neutral and ground
are to be bonded together is at the source only and not the coach. I have
seen the neutral and ground bonded in the heater in the bath where the
wiring got hot and melted through the wire nuts because the wire nuts were
not tight and taped and this was causing the hot skin test to fail. I also
found much the same thing in a 4x4 electrical box in route to the water heater.

I needed to mention the adapter to 110vac should be used for this test.
