When plugged into a non-GFI circuit, it works fine.

The obvious conclusion is that there is a ground fault somewhere in the

There are a few possibilities that my meager mind considered:

1 There is some current in the neutral leg. Multimeter does not
show anything.

Then you're not measuring correctly. There had better be exactly the same
current in the neutral leg as there is in the hot leg.

But if there was exactly the same current in the neutral as hot, then
the GFCI wouldn't be tripping...so maybe he IS measuring correctly! :-)

It is doubtful that he has a meter that will detect 5 to 10 ma differance in
a 14 amp circuit.
That is all it takes to trip a GFCI.
