Are there any localities/states that have made an amendment to accept 8x8 reinforcement wire for the equipotential grid around a pool??
We have a 'buzz' going around here in NJ, but nothing official, in writing yet that I'm aware of.

Florida is bouncing that around as we speak. Most are saying no.

Greg:
I thought I saw that somewhere on the threads, Thanks.

A few pool contractors (EC's) over the last few days said the state (NJ) had a 'memo' out. I have not seen it, nor has anyone else.

Do the guys in your area have the pool builder do it, or does the EC 'build' the grid? My opinion, it should be part & parcel of the pool builder, and the EC should be responsible to properly install the bond.

The way we are starting to see the grid here is they keep coming with the #3 rebar up past the tie beam on the pool shell, 3' out for the pool deck.

I don't think most people have really read all of the changes to 680 and actually figured out what it means. I know it seemed like a shock to Florida once they actually read it (after adoption of course)
The new requirement does use the word "rods" (608.23(C)(1)) and that does preclude wire mesh. This is being revisited in 2008 and it may allow a single ring of 8 copper to bpnd the deck mesh. Around here we don't even see that much mesh. It is fiber in the concrete.

I am one of the views but I really do not know much about this subject.

Article 680 is not one I feel very confident commenting on.

A truly wise man speaks only on familiar items.

Thank you.

PS: I'm not a 680 'maven' either, but it's turning into a hot topic here.

It will get revisited in 2008 and if I read the ROC right we will be able to bond the deck with a single #8 copper loop, connected to the shell in 4 places. The depth of this wire sounds a bit confusing to me. What does

4-6" below sub grade
mean?

4-6" below the grade of the pool deck of course. The pool deck being the finished grade and the sub grade being the bottom of the pool deck.
