Should GFCI have triggered in this scenario


Cutting a galvanized pipe in a home that had been diconnected further down the line several weeks ago. Assumned by now all if any water would have been gone when we drained it.

But there was some remaining water in the pipe where we were cutting.

Should the GFCI that we were plugged into have triggered?

If yes and obviously it did not, what do we need to look at?

Thanks

Why would it have tripped?
Unless water flooded into the tool the GFI could careless what you were cutting.
A small amount on the outside of the tool or on the blades not going to trip it.

The ground fault circuit interrupter trips when electricity has found a path back to the source other than via the neutral wire that accompanies the hot wire (and possibly through your body and with or without the help of water). Such a found and unintended path is referred to as a ground fault when it involves the earth or a grounded object or the ground wire (if any) that accompanies the hot and neutral wires of the circuit.

I've encountered untripped GFCI's immersed in water. No current differential, no trip.

Exactly. you can easily drop a hair dryer into a bucket of water and it simply will not trip the GFCI...
