[VAC] Re: an electrical question

[Dr. Gerald N. Johnson, electrical engineer]

Its safest to pull another ground wire to each receptacle. Connecting
the ground to the neutral at the outlet can be deadly. I've seen that
connection kill. The frame would be far safer than connecting safety
ground to neutral when the neutral opens. Consider installing individual
GFCI receptacles that will operate without a ground connection from the
panel. They will detect currents to ground and disconnect before the
current is enough to cause shock. There is no guarantee that the
individual sheets of the interior wall or frame are electrically
connected.

It would be best if the added ground wire followed the existing wire,
but it would also be effective if that ground wire went down through
walls and passed under the floor to the main panel. Make it stranded
