Bonding in pool areas is intended to reduce voltage gradients in the pool area.

• A. False
• B. True
• C. Not Specified
• D. Optional

Answer: (B)

Bonding pool areas keeps all conductive parts at the same electrical potential. By tying together the pool shell, metal ladders, fences, pumps, heaters, and other metal components with a bonding conductor, any stray current or fault current is shared across a common network, which minimizes voltage differences (gradients) around the pool and on the deck. Because water is conductive, large voltage differences on or near the surface could push current through a swimmer; equipotential bonding reduces those differences, greatly lowering the risk of electric shock. This is a safety requirement for pools, not optional, and it focuses specifically on creating an equipotential zone to protect people in the pool area.
