Electrical question

[Delphinus]

I'm sort of imagining the current as looking like lightning, and I wouldn't want my hand to be between the point of "where's it coming from" and the point of "where it's going to." I would just have to hope that should it ever happen, something will make it stop before it makes me stop.

But apart from that. I am still a bit concerned that the GFCI didn't trip. When I brushed up against the skimmer, the jolt was pretty significant. Probe or no probe, the GFCI isn't tripping. It is on a GFCI though, my tanks are on two different breakers both of which are on GFCI. However it is a mess of extension cords and power bars and timers. Some of which is probably an absolutely no-no like daisy chaining power bars. I wonder if I moved the skimmer pump to a different plug, would the GFCI trip then.

I would hope the thing isn't faulty ..

I guess the thing to do maybe is buy a multimeter and test the amount of current/voltage? Maybe it's not as bad as it felt, and that would explain why the GFCI isn't tripping?

Short of that I'm not sure how to test the viability of the GFCI (other than pressing the "test" button that is!)

I did order a new pump today nonetheless though. I'm just assuming the protocol here is just replace it and move on.
