Pool perimeter bonding

[hhsting]

I have encapsulated reinforcing steel for pool shell. Therefore copper grid is being used in pool shell.

However I am confused about pool perimeter bonding. NEC 2017 says I can use 680.26(B)(2)(a) or 680.26(B)(2)(b) and says to bond to pool reinforcing steel or copper conductive grid at 4 uniform points but then says for nonconductive pool shell bonding at 4 points shall not be required.

Following questions:

1. So does this mean in my case i dont need to bond the perimeter surface grid to the copper grid since my shell reinforcing steel is encapsulated or i can bond perimeter surface grid to the reinforcing steel but thats encapsulated?

2. NEC 2017 section 680.26(B)(2)(a) is it for encapsulated or non encapsulated pool shell reinforcing steel?

Lets start with this easy one:

2. NEC 2017 section 680.26(B)(2)(a) is it for encapsulated or non encapsulated pool shell reinforcing steel?

That ends with "In accordance with 680.26(B)(1)(a)." What does 680.26(B)(1)(a) say? More specifically, what is the first word? If you don't have that it doesn't apply.

Regarding your question #1, you would bond the copper grid to the perimeter wire at 4 evenly spaced locations.

You are getting uncoated steel confused with conductive shells, which are 2 different things.

You must do the perimeter surface but you do not need the 4 points if it is a non-conductive pool shell

If you have used a copper grid in the pool shell, you do not have a non-conductive pool shell. The copper grid is only used with conductive pool shells and it must be bonded to the perimeter in 4 locations. You are confusing the shell reinforcing with the shell itself.
