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.

John

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 know....three (3) replies, AND 344 views?????

Anyone else have any comments???

Guess Greg & I are IT????

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.

Bob:
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.

John

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 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.

So this wire is not in the concrete at all? How does it get bonded? That is certainly a 180 degree reversal. In 2005 you need a 12x12 #8 copper mesh if you don't have 12x12 rebar. I am guessing this is really to bond the dirt under pavers but it sure doesn't read that way.

Rumor again has it that wire mesh 'may' be acceptable. Not laying on soil/fill, 2' of concrete above/below. Tie wire at any 'splices' of mesh; one cell overlap;etc

As there are NO listed clamps (that anyone is aware of) for bonding mesh; tie wiring to rebar may be acceptable.

Bottom line...AHJ call. Nothing official, only speculation, discussion, & rumor.

John

All the views are because of your negative lead-in headline. I think we all took a peak to what this bad subject is that you are bringing up. Kind of like why people watch Jerry Springer.

Effiective tactic though... sells newspapers and gets viewings.

JPS:
No intention of a negative lead-in 'headline', and views & papers are of no interest to me either.

Here in NJ, this has been a 'BAD' subject, & there is still a lot of confusion and rumors floating around.

John

I understood immediatly where Hot was going with this. The same issue is still being argued about in Florida where there are "no local exceptions" (the NEC is adopted, unaltered, statewide, by law) but there are still local "interpretations". We still have AHJs who say mesh is, or should be, OK.
