The bonding grid conductor for pool components must be a conductor of what material, not smaller than 8 AWG?

• A. Stranded Copper
• B. Aluminum
• C. Solid Copper
• D. Copper-Clad Steel

Answer: (C)

Bonding grids for pool components are required to be copper because copper provides a dependable, low-impedance path that resists corrosion in wet pool environments, keeping all metal parts at the same electrical potential. The 8 AWG minimum sets a size large enough to carry fault currents without excessive voltage drop or heating, ensuring safety if a fault occurs.

Solid copper is listed as the material in this context because it offers robust mechanical connections and consistent electrical contact at clamps and lugs around the grid. While copper is copper whether solid or stranded, the standard practice for the bonding grid emphasis is on using a solid copper form for reliable connections and continuity. Aluminum or copper-clad steel introduce higher impedance or corrosion concerns, and are not appropriate choices for this bonding conductor.
