The GFI works on the unbalance of current between live and neutral.
Ground may not come into it at all (despite the GFI designation).
So suggestion: Maybe you touched both live and neutral wires that the
mice had chewed so as be bare, simultaneously and electric current
went through your hand but live and neutral currents being balanced,
it did not trip the GFI?
However if current went from your hand through your body to the damp
ground it's a good question; one would think that would be an
unbalanced current that would trip the GFI?
Also could anyone comment on the amount of current through human body!
Even a few milliamps, not enough or fast enough to trip the GFI could
shock??????
Assuming, although not stated, for the moment this is typical North
American/Mexico etc. 115 volts circuit etc. Not European style 230
volts etc.
