What Is Bonding?
Bonding is an electrical connection that joins metal parts so they stay at nearly the same electrical potential. Around a pool, bonding helps reduce voltage differences between parts a person might touch. It is a protective measure used with other parts of the electrical system.

- A GFCI doesn't replace a pool bonding system.
How Bonding Works

Bonding works through a continuous path between connected metal surfaces. A bare copper conductor often forms part of that path. Connectors join the conductor to pool equipment and other metal parts. Related service: Pool Wiring.

The connected parts can rise or fall in voltage together. That limits the voltage difference between surfaces within reach. A loose connection can break the path and leave a part separated from the bonding system.
Grounding has a different role in an electrical system. It connects the system to the earth and supports other protective functions. A pool also has equipment grounding, which provides a path for fault current back to the electrical source. Bonding and grounding work together, but the terms aren't interchangeable.

From the Chris Miller Electric team
When we work on pool wiring, we look at the bonding connections near the equipment. We check that the conductor and connectors are intact and suited to the parts they join. We also consider whether equipment changes affect the existing bonding path.
Bonding in Practice: A Real-World Example
A pool pump is replaced during a wiring project. The electrician checks the bonding connection at the new pump and its link to the existing pool bonding system.

Grounding
Grounding is an electrical connection that links a wiring system to the earth through a conductor and a grounding electrode.
Ground Fault
A ground fault is an electrical fault that sends current onto an unintended path to ground.
GFCI Outlet
A GFCI Outlet is a receptacle that shuts off power when it detects a ground fault.
Open Ground
An open ground is a break or missing connection in an electrical circuit's equipment grounding path.
