Bonding vs Grounding
Bonding and grounding are two very different things that are often confused. Grounding serves two purposes. First, a ground conductor provides a low resistance path to conduct lightning strikes to the earth. Second, grounding provides a low resistance path for hot wire shorts to conduct enough power back to the main panel to trip the circuit breaker. Bonding is about making sure that any electrical current that is present around the pool goes through the bonding wire instead of going through you.
