Push the test button and see if it trips.

The GFCI is suspose to trip at 5 ma. Most people can feel currents as small
as 1 or 2 ma. The test button is set for about 8 ma. Incase you don't hae
a point of refferance, a 100 watt light bulb will need about 1 amp of
current to light. A ma is .001 of an amp. Up to about 10 ma on the outside
of the skin is usually safe but it might start being painful. Get up to 50
to 100 ma and you could die. Those are very rough numbers.
