Equipotential bonding around pool

[JoeNorm]

I have completed the bonding grid around a new pool with a combination of rebar and #8 solid wire. There are already (3) #8 stranded and insulated wires coming into light niches from the supply panel.

My final wiring to complete is at the cover motor area, I have a #8 solid exposed here that is part of the grid. There are a few raceways back to the panel.

Do I need to bring another stranded #8 here? Or is the #12 EGC that will come with the cover motor wiring enough? I can't imagine I should bring a solid wire all the way here but it would not be impossible.

thanks for the suggestions

What code year are you on?

There are two things to consider with a pool.

1) Equipotential bonding - 680.26

Your equipotential bonding is required to be a solid #8 (or other approved method) and needs to interconnect all the items in 680.26. This results in effectively creating a equal potential to all parts around the pool. Such that any unintended contact or normal use while wet will not result in a shock potential / voltage gradient.

2) Equipment grounding (and bonding) - 680.7 / 680.8

Your branch circuits or feeder circuits will need to also have a viable ground fault current path back to it's source, which is where the equipment grounding comes in. That portion is more or less the same except they require the wire type in equipment grounding methods to be more resilient. This also depends on which code you have. The sections are 680.7 & 680.8.

If you have the 2023 edition of the NEC than your EGC must be copper and insulated and not smaller than #12 copper and sized based on 250.122. I would consider most locations around the pool "wet".
