NEC Article 680: Swimming Pool Electrical

NEC Article 680: Swimming Pools covers equipotential bonding through pump motor circuit. This guide explains each major section with practical interpretation for electricians.

680.26 Equipotential Bonding

All metal within 5 feet of the pool must be bonded together with #8 solid copper: reinforcing steel in pool shell, metal coping, ladders, handrails, diving board, pump motors, heaters, light niches, and metal piping. The pool water itself must also be bonded via a listed water bonding device or conductive pool finish.

This creates an equipotential plane - everything at the same voltage so no one gets shocked.

680.44 GFCI Protection

Every circuit supplying pool equipment requires GFCI protection - pumps, heaters, lights, receptacles, everything. Receptacles within 20 feet of the pool must be GFCI protected. At least one 125V receptacle must be installed within 20 feet of the pool for maintenance equipment.

680.23 Underwater Lighting

Underwater luminaires must be listed for the purpose and installed in forming shells. The junction box for underwater lights must be at least 8 inches above the water level and at least 4 feet from the pool edge. Low-voltage (12V) systems reduce shock risk but still require GFCI.

LED pool lights have largely replaced incandescent.

680.8 Overhead Conductor Clearances

Overhead power lines must clear the pool: 22.5 feet horizontally from the edge of the pool for any conductor. 14.5 feet vertically above the pool, diving structures, or observation stands. These clearances are frequently cited as reasons pools must be relocated during planning.

680.21 Pump Motor Circuit

Pool pumps require a branch circuit based on motor FLC (full-load current). Modern variable-speed pumps draw significantly less than traditional single-speed pumps. Disconnect required within sight of the pump motor. GFCI required for all pump circuits regardless of voltage.

Frequently Asked Questions

What does NEC Article 680 cover?

Article 680 covers swimming pools requirements. Key sections include 680.26 Equipotential Bonding and 680.44 GFCI Protection. It applies to all electrical installations in the United States.

Where can I find the full text of Article 680?

The full NEC is published by NFPA and available at nfpa.org. Many libraries provide free access. Your local building department also has copies available for reference during permit applications.

Does Article 680 apply to existing wiring?

The NEC applies to new installations, modifications, and additions. Existing wiring that was code-compliant when installed is generally grandfathered unless a renovation triggers an upgrade requirement. Check with your local AHJ (authority having jurisdiction).

When did the current Article 680 requirements take effect?

NEC 2023 is the current edition. Adoption varies by state. Check your state adoption status on our state code pages.
