What Is an Equipotential Bonding Grid

Briefly, an equipotential bonding grid is a metallic grid that establishes an equipotential plane (or Faraday Cage) around the pool and deck. … The equipotential plane puts all points on the plane at an equal potential to equalize voltage and current that passes through the plane.

What is the main purpose of equipotential bonding?

Protective equipotential bonding is a method of applying a low impedance path from exposed-conductive-parts to extraneous-conductive-parts, to ensure equal potential throughout the installation thus preventing a hazardous potential difference occurring between such parts in the event of a fault.

Does my pool pump have to be bonded?

The NEC requires that all electrical equipment, except double-insulated equipment, be bonded together. In addition, all metal within 5 feet of the inside of the pool wall must be bonded with the equipment to form the equipotential bonding grid.
