As the coils heat up they may leak enough current to ground to trip the GFI

Agreed, and so you know what to look for, anything less than 50,000 ohms
is likely to cause that GFCI to trip.

A 1650 Watt element will go on momentarily but then causes the 20 Amp
GFI to break.

I tried it on 2 different GFI breakers.

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


There are a few possibilities that my meager mind considered:

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

2 Buy a higher Amp GFI.

3 The GFI is more sensitive to a load near its 20 Amp rating.
1650Watts/(20 x 115)

4 And the no-no answer, replace the GFI with a non-GFI breaker.

Any suggestions?
