I've lurked and searched here for about year while planning my above ground pool, yet there's a question I have that often comes up but I haven't seen completely answered.
I'm installing a Sharkline Matrix 18' above ground pool, which has all resin components besides the steel wall.
I understand the reasoning and logic behind electrical bonding, and I understand why a single bonding lug on the wall seam connected to a typical bonding ring (and must be connected to pool water and pump system) should be sufficient for bonding. And drilling holes in my pool wall for 3 additional equally spaced bonding lugs voids the warranty and creates opportunities for rust.
HOWEVER, my electrical inspector said he's bound to the Electrical Code which requires 4 equally spaced connections from the bonding ring to the pool, and wants me to drill holes for bonding lugs where the pool coving will cover.
I'm looking at the 2020 NEC code, and it says bonding at 4 points shall not be required for nonconductive pool shells, in which case a copper grid is required. Which would be very expensive.
Has anyone found language in the code that allows for a single point of connection to the pool wall on an all resin pool without a copper grid? The only solution I can think is to drill the holes as described by the inspector, and cover them with encapsulating resin to protect from corrosion.
