This is what I metered this weekend:
At the subpanel in my barn, where the dilema exists, the neutral and ground
bars are not attached to one another. Between the two hot legs I get 234vac.
The ground is a UFer, a piece of rebar in my foundation. I meter 148vac
between ground and one of the hots and 88vac between ground and the other hot
leg. I meter 119vac between each hot leg and neutral.
At the actual receptacle I meter 28vac between the large slot or neutral and
ground, and the same at the subpanel.
I would think I should see the same voltages between each hot leg and ground
and neutral? Or another words the neutral and ground should be at the same
potential?

Karl,
I like your logic. It is certainly more straightforward than the twisted
chain of logic I came up with: I remember "Wide White" to remember
which
wire goes to which blade. How do I remember that the white wire is the
neutral wire? Well, if you're looking into a dimly lit electrical box
which
wire would be hardest to see? The black one. Which wire is the dangerous
one? The black one! Sounds like some kind of plot to at least shock if not
kill non-electricians to keep them from putting their un-trained hands in
there!
