If the neutral isn't broken between you and the panel, the _maximum_
ground-neutral voltage you'll see in the OP's scenario is a volt or two.
That depends entirely on how well you are (or aren't) grounded. Under normal
circumstances, there won't be enough current to do any damage. One sweaty hand
on a grounded junction box, and the other sweaty hand touching an active
neutral, though...
and you might have 5% as much conductivity as the neutral and see 6v.
Pardon me if I don't simply take your word for it. Got any calculations to
back that up?
I didn't think so...
Not likely but possible.
Harmless, but possible. Stupid, but possible. Doug, but absurd. Oh, that
is redundant.
How much does it take to kill, Wade?
Hint: the trip threshold on a GFCI is 20 mA.
When are you going to figure out that neutral and ground are NOT the same?
In the USA the trip threshold on a class A GFCI is five milliamperes.
On a class B GFCI such as the ones built into AFCIs the trip level is
thirty milliamperes. Class B GFCIs are only intended to protect
equipment.
