The funny thing about that is every picture of Al he is using the shovel, every picture of Chris he is leaning on the shovel. :grin:

Chris, the 12" x 12" grid is for conductive pool shell walls such as poured walls and spayed walls. The copper grid is used where no reinforcing rod or mesh is used in the walls.
The requirement for perimeter surfaces is either reinforcing rod, wire mesh or if none is used, a single # 8 awg copper conductor.This single conductor is not required to be in a 12 x 12 pattern. One run 18-24" out 4-6" deep or just under the pavers.
This is from the 2008 version.
I would get the pavers peope to put the wire mesh under the pavers and ty wire them together and then do the regular 4 point bonding with the # 8.

The #8 goes in the GRADED DIRT before the beding sand. The 12" copper grid requirement was done away with by a Judge. Way to costly. If using concrete deck, simply attach the #8 ring to the normal steel wire mesh in 4 places or to steel rod mat provided by the pool builder.

Butch, would you have a link or maybe steer me in a search direction?

In my decktop at home. Monday night is as soon as I can get to it. Cost not mentioned in the ruling but you get the idea. Copper mat replace by #8 ring....yada, yada, yada as mentioned in the thread.

What I have is the wording of the 2008 NEC. It was added as an adendum to the 2005 NEC by some Florida Judge.
 


Looking at the coping around the top of the pool, aren't we already late in getting the e-bonding grid in? It would need to be under the coping around the rim of the pool.

I got a steel bond inspection and a #8 is sticking out under the coping on all four sides. There are 2 pieces of steel just under the coping that run around the entire perimeter. Did I miss something?

If he is under the 08 the perimeter bonding wire can be 24" from the inside wall of the pool

Are you under the '05 or the '08?

[quote='05]... The equipotential common bonding grid shall extend under paved walking surfaces for 1 m (3 ft) horizontally beyond the inside walls of the pool...[/quote]
[quote='08]...The perimeter surface shall extend for 1 m (3 ft) horizontally beyond the inside walls of the pool and shall include unpaved surfaces as well as poured concrete and other types of paving.[/quote]
The grid, not the four point bonding, seems to be required to start where your belly button touches the pool wall when you're in the water.
 
George Stolz said:
Sorry to contribute to that. :D

Okay, so under the '05, the requirement is more restrictive than the '08, looking closer. The '05 requires a gridwork be constructed, whereas the '08 allows a single conductor.

Yeah, but if you read MD's link, the 08 wording is there. Effective date 10/18/07. We don't adopt the 08 until June or July.
