    Check my understanding of bonding.

    I've read up here and the NEC code and I think I've got it.

    I'm re-decking an old in-ground liner pool with pavers. I can't see any evidence of any previous attempts at bonding on it, so I'm on my own. What I planned on doing is putting a loop around the entire pool with #8 bare copper wire and tying it to the metal pool walls in 4 places. Also tied to this loop will be the mounting cups for the two stainless ladders. Then a leg comes from this loop and ties to the bonding lug on the pump motor.

    Is this basically it? I have no lights or step rails to so they are not a concern, and the fence is over 5 feet from the pool edge.

    Does it matter what the depth of the bonding loop below the pavers is? I have the option of putting it on the dirt below the base gravel or in the sand/quarry dust below the pavers.

    According to the 2008 version of the code, the bonding conductor must be secured within or under the perimeter surface, 4 to 6 in. below the sub grade.

    Just to add from 2008 NEC 680.26:
    Bonding conductor must be 18 to 24 in. from the inside walls of the pool.

    OK got it, 4-6 inches into the soil below the gravel paver base and 18-24 inches from the perimeter of the pool walls. That's clear enough.

    The rest of the plan sounds good?

    That all sounds fine. My only concern would be: If you need to pass an inspection, you might want to talk to the inspector before hand and make sure that approach is alright in your area. There are still a few places where a full conductive grid is required under pavers (though that has become uncommon).
