680.26(B)(1)(b) Copper Conductor Grid

[Ravenvalor]

Hello,

Has anyone had to construct a Copper Conductor Grid required in Art. 680.26(B)(1)(a)? It looks like a lot of work. It almost seems like rebar should be allowed.

Thanks

680.26(B)(1)(a) does permit the rebar to be used as the bonding grid, unless it is epoxy coated to make the outer surface non-conductive.

So the term they use "Structural Reinforcing Steel" does not refer to the steel walls of the pool?

Thanks....

The section is talking about concrete pools in general, there would be no steel wall in that type of pool.

I ordered a roll of copper #8 solid grid with 12" x 12" squares in 2-feet wide for perimeter bonding around a pool in 2005 when the Code first had the new 680.26 requirement. It came from Harger grounding products. Just rolled it out and cut it at the corners of the pool. Connected the end cuts with DB burndies.

Now the industry thinks a single #8 provides protection. Well it does not.

.

Is rebar

The pool that I am wiring has stainless steel wall panels encapsulated in a non-conductive compound. 680.26(B)(1)(a) seems to imply the necessity of a Copper Conductor Grid.

That section does not apply pools with non-conductive walls. There is no bonding required for non-conductive walls. You will have to bond the water and any perimeter surfaces.

Great news to hear. I will make sure the inspector is on the same page as us with this interpretation.

Thanks
