Ground Fault Isolators (GFI's)
We have been having problems with loss of power at receptacles inside our garage and outside on the patio. Bruce, our favorite electrician, replaced one of our GFI receptacles that had been kicking o...

There is a problem with the hypothesis. The GFCI compares the current flowing thru the hot connection to the current flowing thru the neutral connection. A difference of 5-6 milliamps will cause a trip of the GFCI. That current flow should be exactly the same in both. If there were 5 amps flowing thru the hot wire (and therefore 5 amps flowing thru neutral) and it induced 10 milliamperes current thru the ground wire, that does not mean there would be any change in the flow thru hot and/or neutral. Those current flows would still remain identical unless there were a leakage somewhere. And an induced flow in a ground wire is not leakage and would not cause s trip. The GFCI does not do a compare to the ground wire.
