What Is Bonding?

Bonding is an electrical connection that joins metal parts so they stay at a similar electrical potential. Around a pool, bonding links parts such as metal rails and pump equipment. This connection helps reduce voltage differences between surfaces that a person might touch.

Local relevance: Miami's humid coastal air can expose pool equipment connections to moisture and salt, which can speed corrosion at bonding fittings.

Key Takeaways About Bonding

  • Bonding connects metal parts that may not carry current during normal use.
  • Corrosion can weaken a bonding connection.
  • Grounding and bonding serve different purposes.

How Bonding Works

Bonding works through a continuous path between connected metal parts. A bonding wire and its connections help those parts stay at a similar electrical potential. You can think of electrical potential as the electrical pressure at a surface. Related service: Pool Electrical Repair.

A voltage difference can appear when connected parts lose that path. A loose or corroded connection can interrupt it. The condition of the wire matters, but the contact at each end matters too.

Grounding has a different role from bonding. Grounding connects an electrical system to the earth, while bonding joins metal parts to each other. A ground fault circuit interrupter, or GFCI, also has a separate role. It detects certain current imbalances and shuts off power.

From the Earth Electric team

When we handle pool electrical repairs, we look at bonding connections near the equipment we service. We check for loose fittings and corrosion that can affect contact. A connection may look intact while the metal beneath a fitting has deteriorated.

Bonding in Practice: A Real-World Example

A pool pump needs replacement after its motor fails. During the repair, the electrician checks the bonding connection at the pump and addresses a corroded fitting.

Related Terms

Electrical Grounding

Electrical Grounding is a connection between an electrical system and the earth.

GFCI

A GFCI is a ground-fault circuit interrupter that helps protect people from electric shock.

Ground Fault

A ground fault is an electrical fault that sends current along an unintended path toward ground.

Fault Current

Fault current is electrical current that flows along an unintended path because of a fault in a circuit.
