Hi Ron and all,
Actually the name GFCI is a bit misleading I think. You don't need a ground
for a GFCI to work. That's why they recommend their use in upgrading two
wire systems. The GFCI senses a current difference between the neutral and
the hot wire. If the difference is greater than 5 milliamps, the GFCI is
supposed to trip and disable the circuit. Thus if you get a shock and the
GFCI trips you were in essence the "ground fault" in "Ground Fault Circuit
Interupter". Having a third wire as ground is nice to have, but it seems
that putting a GFCI in a two wire circuit greatly increases the safety of
the circuit.
Steve, W2MY

Don makes a good point about running a ground wire through the house, at
least to the critical outlets near the ham shack. I'd include, as a minimum,
kitchen and bath outlets as well so they can be equipped with ground-fault
interrupters.
