What is the purpose of a bonding jumper in a swimming pool installation?

A bonding jumper plays a critical role in ensuring electrical continuity within a swimming pool installation. Its purpose is to connect various metal parts and equipment together, forming a low-resistance path that helps maintain an equal electrical potential among all bonded components. This is crucial for safety because if any part of the installation were to become energized, the bonding jumper would allow the current to flow safely back to the ground, reducing the risk of electric shock or electrocution to users of the pool.

By achieving this electrical continuity, the bonding jumper also helps to mitigate differences in voltage between various metal elements, which could lead to dangerous situations. Proper bonding is mandated by electrical codes and standards to safeguard against electrical hazards in environments that are prone to moisture, such as swimming pools.
