Here is a good one, we all know what to test on a GFCI, but do we know why?

Sorry I disagree I believe it is E.
If you get between the hot and neutral the GFCI will not trip you make a complete balanced circuit. . The GFCI only gives you protection from the equipment if you get between the hot and ground .
Example a curling iron the shorts to the case and you grab the sink or tap then it will dump.
You can also buy a GFCI that is has a higher trip rate then 5 Milli amps.
Roy Cooke sr Brighton Ont .

d. to protect against shock and will trip at 5 milli amps
92% [ 51 ]
e. none of the above
7% [ 4 ]

I thought a GFCI measured the difference between neutral and hot? A ground is not required for a GFCI to operate. But if you are touching the iron and the sink the difference between the not and nuetral will decrease tripping the GFCI?
