Actually... the way a ground fault circuit interupter operates is it
monitors the ground path. any leakage to ground (as little as 1/1000th of an
amp) will cause it to trip. If you look at the male plug on your heater you
will notice that it has no ground, thus the GFI will not trip in a ground
fault situation. So to contradict you Roy, it is current flow (to
ground)that causes a GFI to trip. Resistance has no effect on the GFI
whatsoever. Kurt tex1 at airmail.net

GFI outlets only trip when they can detect a
