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.) --Steve Bellovin, http://www.research.att.com/~smb (me) http://www.wilyhacker.com (2nd edition of "Firewalls" book)
