[R-390] GFCI issues

[Bill Hawkins]

Thanks, Joe. Missed that, after so much discussion of GFCI outlets and
R390 filters.

It is still all about unbalance in the power circuit of line to neutral.
A 15 K or 0.1 mfd from hot line to anything besides neutral should trip
the breaker. Perhaps a mouse or squirrel fits those parameters.

It takes a lot lower resistance from neutral to ground to unbalance the
power circuit, but it can be done. Only the line and neutral wires go
through the detector toroid. The ground wire is just a safety ground. It
plays no part in fault detection unless it happens to carry all or part
of the fault current. A fault to a conductive water pipe can also
unbalance the circuit. A megger from disconnected and shorted line and
neutral to a ground that can carry current would be a good thing to try
if a new GFCI breaker doesn't fix it.

Yes, but a GFCI breaker was mentioned in the discussion, that would mean
that the wires from the panel would be in the circuit.
