ECN Forum Forums Code Related Discussion NEC & other Code issues Rebar bonding connection...

Redsy, If the code allows to tie wire a ground to rebar, then a direct burial acorn clamp should be O.K. Just get some 3M Scotch coat, and coat the connection. If not, get it from Greaves.

Redsy:

Here's a picture for us to see and a Greaves part number if that helps.




I have an image of a ground clamp that looks just like the same one used on a water pipe or water tubing, and it shows where it is OK for use in a concrete location.

The only problem is that it says: "Approved" and not: "Listed" and we all know that UL DOES NOT APPROVE EQUIPMENT.

If you want I can post it here, let me know.

Thank you Joe, that is exactly what I was thinking of. I couldn't find one to take a picture of the last few days.

Thanks Joe & Ryan for your efforts.
That is the Greaves rebar clamp that I have literature on.
I believe the "J29" means 3/8" rebar, because J30 & J31 are for 1/2 & 5/8", respectively.
The "DB" obviously means direct burial.
Joe,
The literature I have shows the UL listing symbol and the CSA symbol with NRTL and Direct Burial incorporated into the symbol.

Here's the other clamp I mentioned above.

Thanks, Joe.I noticed the copper screws on what appears to resemble a standard water clamp, probably smaller diameter, though.
Is that a Greaves item, or do you have a manufacturer or part number?

I was always curious, and now seems like a good time to ask (learn). Why is it important/required to bond all the rebar in an inground pool?

I don't know who manufacturers this clamp.
