What Is a Bonding Jumper?
A bonding jumper is a conductive connection between metal parts that keeps those parts at the same electrical potential and provides a low-impedance path for fault current. In pool wiring, the jumper may connect metal equipment, enclosures, or bonded components within the equipotential bonding network. It supports consistent electrical continuity across connected parts.

Key Takeaways About Bonding Jumper
- It connects metal parts within a bonding network.
- Continuity matters more than the jumper’s physical appearance.
- A bonding jumper is not the same as a grounding electrode.
How Bonding Jumper Works
A bonding jumper creates a conductive bridge between metal parts that must remain electrically connected. The connection carries fault current through the bonding path and helps keep connected parts at a similar electrical potential. Its practical value depends on a sound connection at each termination.

In pool wiring, a jumper can connect a metal enclosure, equipment component, or other conductive part to the equipotential bonding network. An electrician checks the connection path for continuity and examines terminations for looseness, corrosion, or damage. The jumper works as part of the complete network, so a sound individual connection does not compensate for a broken path elsewhere.
From the Center Electric Service team
When we inspect pool wiring, we trace each bonding jumper between connected metal parts and check the continuity of the complete bonding path. We also examine terminations for corrosion, looseness, or physical damage because a clean-looking jumper can still have a poor connection.
Bonding Jumper in Practice: A Real-World Example
A pool pump has a metal enclosure that must connect to the pool’s equipotential bonding network. A bonding jumper links the enclosure to the network so the enclosure remains electrically connected with the other bonded parts.
