Grounding Probe

[monza]

I don't think a grounding probe would do what it is supposed to do, collect stray voltage form your water if it was on a GFCI circuit, it would pop the GFCI. You'd be better off with what ever hardware your worried about leaking stray voltage on the GFCI. I'm not a electrician and could be totally wrong however...

I have read that using a grounding probe along with a gfci is the fastest way to cut power going directly into the tank, thus providing a milli second shock instead of making funeral plans

I use both. Might as well provide a path for the GFI to trip if there was leakage ahead of time rather than system waiting for me to but my hand in.

I thought using a ground probe with a gfi is dangerous, since the probe may interfere with the gfi and the gfi will not trip...then Zapp! Gotcha
