Bonding existing coping

[joshua5438]

I have almost completed bonding items in the pool that for some reason seem to have never been bonded. The pumps, water, concrete and light are all bonded but the ladder, handrail and coping are not. I cut notches in the concrete and bonded the ladder and the handrail to the existing bonding. Now I have to figure out how to bond the coping. Anyone have any recommendations? I can the the wire to the coping but not sure how to connect it. All I can think it to remove a portion of the concrete at the coping and install a bonding lug. What type of screw should be used to attache the lug to the coping?

I assume you have aluminum coping which the concrete goes right up to. my understanding is that bonding should be connected to coping at multiple and roughly equally spaced intervals around the perimeter. 4 or more locations. It could be connected via copper ring terminal and self taping screw or at least that is allowed in my Canadian province.
Gonna be hard to do with concrete in place.

Is absolutely every electronic component on a GFCI protected circuit? That’s something I would make sure of and possibly forgo the bonding.

You are correct on the aluminum coping. All pumps and lights are on GFCI breakers. I know everything else is bonded at this point but my daughter had a cut on her hand and touched the coping and it shocked her. That's actually the way I discovered the handrail was not bonded. I grabbed it last year with a paper cut on my finger and it shocked me. Nothing strong, but anything it more than I want! I may do like i did last year and run some temporary bonding wires to see if I can get everything equal and then figure out how to permanently attach it. I may have to core drill several holes around the pool and then chisel out to get to the back of the coping. Concrete will be covered with pavers in a few years so not too worried about concrete not matching.
