It's called various things, you're probably thinking of power factor or maybe
phase angle (which are different ways of looking at the same thing).
But, it shouldn't trip a GFCI, since a GFCI is supposed to operate only on
current. It doesn't care if the current is out of phase with the voltage.
I run a half-horse submersible pump off a GFCI, and it's never tripped it.
