  1. 8 AWG ✔
  2. 14 AWG
  3. 12 AWG

Why: Section 680.26 uses a solid copper bonding conductor, 8 AWG or larger, which may be insulated, covered or bare. Its job is to reduce voltage differences around the pool.

Huh, didn't know that: Instead of 8 AWG copper, rigid brass conduit or another identified corrosion-resistant metal may be used.
