Did you mean 5A, or am I misunderstanding GFIs?
5ma is correct.
It takes very little current to cause fibrillation.
GFI's compare the current going out the hot lead of a receptacle
with that coming back the neutral. If there is more out than back,
it makes the assumption the rest is going through Jill Winecooler/
Joe Sixpack to ground, and trips.
