Pool Bonding

[keith gigabyte]

Bonding an inground pool..
the set up. metal shell with a removable ladder and 1 metal shell light. Plastic steps no railing. Concrete deck 8 foot wide around perimeter. aluminum coping zip screwed to top of pool shell

My question is do I need to drill and screw/bolt with machine screws the coping to shell? I intend to bond with #6 to shell at 4 points per 680.26 B 2
I am going to use direct burial lay in lugs through bolted to 4 points around shell.
Also I will provide pigtails to be used on ladder sockets (removable ladder). and pig tail for slide anchors. I also plan to leave some loops for attachment to mesh used in concrete deck.

My main question is do i have to bolt the coping (its in sections about 6 foot long. Im assuming the zip screws used by pool company are not approved electrical connection.
thanks
for any help

You're going to want a compression type bolt / nut set up . As it may not be thick enough for many threads. Does the pool have any specs? Some inspectors (if any in your county) can get confused. I've heard of them wanting every panel bonded individually. That's why the specs would be good to know. Or some times there will be a phone number for tech support.

I had an inspector that required bonding under the coping. The problem was, it was only short sections of track that the liner attached to. These were not continuous, and he wanted a lug on each section with a loop of #8 run through and pigtailed to the perimeter ring. I told him I didn't think the little metal (aluminum) strips could be touched as the stone coping covered them. Also, the pool was concrete with fiberglass rebar, so nothing conductive there. He would have nothing of it so I had to bond them all. These strips were so thin I had to drill a hole then put a bolt, lock washer, and nut to hold the lug. These all had to be stainless.
As Buck says, it depends on the thickness of the metal whether you can tap it or use a bolt & nut.
