Hidden Danger After Pool Equipment Replacement: A Missing Bond Can Cost You

The image to the right shows a disconnected bonding conductor at a pool pump motor—a condition we frequently encounter during our inspections. In many cases, the replacement motor either lacks a bonding lug or the original lug is too corroded to reuse, leaving the bonding system unintentionally broken. Even well-intentioned people forget to account for these matters, especially when they do not understand the serious danger posed by a disconnected bonding wire.

Bonding is not optional—it is critical life-safety protection. The National Electrical Code (NEC) requires that all metallic parts of pool equipment—including pumps—be bonded together to maintain equal electrical potential and reduce shock hazards. (InterNACHI)

When this bonding connection is missing:

• Voltage differences can develop between equipment and surrounding surfaces

• Stray or induced voltage may energize metal components

• A swimmer or a nearby person can become the path to ground and experience an electrical shock

Bonding exists specifically to eliminate voltage gradients and prevent electric shock by ensuring all conductive components are at the same potential. (InterNACHI)

Practical Takeaway

If your pool equipment has been serviced or repaired, always have a qualified electrical inspection performed immediately afterward. Never assume bonding was reconnected correctly.
