Re: Hot Tub sitting on Pavers!
Funny you should mention the cost.Because the listed pressure connectors,I was speaking of in my posting "(X)" or really like "(+)" for the prefab grid in field..
Got it on good authority..The connectors I seen are manufactured by "NSI" and sold for $3.95 each.

For a 12' x 12' grid (Not including the part Under the tub, just the 3' around it)... I come up with 140 cross sections!
Holy Shnykies!

Re: Hot Tub sitting on Pavers!
Let's see, if my math is correct, it's actually cheaper to add an inground pool and use it's steel instead of building the copper grid!!!

680.26 Equipotential Bonding
(A) Performance. The equipotential bonding required by this section shall be installed to eliminate voltage gradients in the POOL area as prescribed.
Where does the NEC require an E-Grid (as I now call it!) for a Hot Tub?

I don't envy you guys out there trying to tell customers how much needs to be done and how much it will cost.

Re: Hot Tub sitting on Pavers!
Yea, I don't envy myself right now. Looks like I will need to make a call and explain to the customer I need to add about $500.00 to the job cost after I already gave them a quote. :roll:

Re: Hot Tub sitting on Pavers!
Honestly, I plan on pleading my (Unbroken wire) case to the AHJ to see what they say.
It really shouldn't be necessary (to bond all the crosses) and I have the feeling they will see my point. I really think it is only important when two different wires cross not the same wire. I realize there is a slight, and I mean slight (Approx. 0.000764 ohms per ft.)difference in the resistance of the length of wire but man...that's a pretty weak argument in my opinion.
We'll see, I'll talk to them and I'll let youz guyz know what they say.
Thanks for the input.

Not to be a party pooper, but $500 may be a little on the low side - price this stuff, then tell them.
I believe that this copper mesh comes with a suit of armour to soften the blows that will follow the price announcement

Re: Hot Tub sitting on Pavers!
You're probably right Pierre, I was just approximating.
I'm trying to think of an alternate way around this E-Grid. Not to undermine the NEC, just to give my customer an option when I present this whole mess to him.
The only thing I can think of that would look nice and be effective would be to build a 36" wooden deck/step around the tub.(Probably just as expensive!)

Re: Hot Tub sitting on Pavers!
Hi Dave
Im wondering where it says you don't have to have a EBG if you have a wood walking platform (deck)?

Re: Hot Tub sitting on Pavers!
Jim, I don't think a wooden deck would be considered a "paved walking surface" in 680.26(C).
Neither would crushed stone, or grass, or mulch, or astro-turf! I just think the wooden deck might look the best!
Like I said, I'm just trying to give the customer options, not trying to dodge the NEC.
Editted to add: By the way, I already checked... Paved Walking Surface is NOT defined in the NEC!

Re: Hot Tub sitting on Pavers!
To me this section needs clarification, as the whole thing seems to be written for in- ground swimming pools with hot tubs just being an afterthought.
You're right about that Dave, but where in 680.26(C)does it say you dont need a EBG if you dont have a "paved walking surface"?

Re: Hot Tub sitting on Pavers!
680.42 says hot tubs must comply with Parts I and II of this article which includes article 680.26(C).
Could it be that 680.42(B) is saying that we dont have to go by 680.26(C)? (a stretch in my opinion)
I still havent seen a reasonable solution to installing a hot tub on an existing deck if we must install a EBG per 680.26(C)
There is a recent thread that did not come to any conclusions either.

Does anyone have Mike Holt's Grounding vs. Bonding book? What does it say?
