At a pool trade show i went to earlier this year, a presenter said he was working on the next (or most recent?) NEC code which exempted concrete pools from having to use a seperate water bond, assuming the pool has an equipotential bonding grid in the concrete shell. It made sense to change this code because once the concrete is hydrated from the pool water it is in contact with the rebar inside of the concrete. However, i cant find this change online anywhere because its a fringe topic. does anybody know where i can look this up to show an inspector?
