How many zones are established by NEC Article 680 around pools?

The correct answer is three zones. NEC Article 680 establishes three specific zones around pools to ensure safety and proper installation of electrical equipment in the vicinity of water. These zones are designated as Zone 0, Zone 1, and Zone 2.

Zone 0 is the area located beneath the surface of the water in the pool, where certain requirements are established for the installation of lighting and other electrical equipment to minimize risks associated with electric shock.

Zone 1 is the space above the water surface and extending to a specified height vertically above the pool edge. This zone has strict requirements to protect against potential electrical hazards, as it is where conductive components are most likely to come into contact with water.

Zone 2 is the area extending outward from the edge of the pool, which is also where specific safety guidelines apply to electrical equipment and wiring, ensuring that they are installed safely away from the potential influence of water splashes.

This three-zone system helps clarify where certain types of equipment can be installed and what safety precautions must be taken to avoid electrical hazards in wet locations. Understanding these zones is critical for ensuring that installations comply with the NEC and promote a safe environment around pools.
