Thus spake joe mcguckin <joe@via.net>:

It only takes 30ma to put your heart into atrial fibrillation. In the
usa, gfi's are set to trip at 5ma.

Did you mean 5A, or am I misunderstanding GFIs?

No -- 5 ma is correct. (GFIs measure the difference in current between
the hot and neutral leads -- if it exceeds 5 ma, it trips.)
