What guidance does NEC Article 680 provide regarding wiring methods in pool areas?

NEC Article 680 provides specific guidance regarding wiring methods in pool areas to ensure the safety and reliability of electrical installations in potentially hazardous wet environments. The correct answer emphasizes that wires must be installed in a raceway or using methods that are suitable for wet locations.

This is crucial because the proximity of water increases the risk of electrical shock, and using raceways or wet location rated materials helps protect the wires from moisture and potential physical damage. The raceway provides a barrier against water intrusion, while materials designated for wet locations are designed to withstand the harsh conditions present in areas like pool decks or near hot tubs. Proper installation practices, as outlined in Article 680, not only ensure compliance with safety standards but also enhance the longevity and performance of the electrical system in those environments.

The other options present practices that would not align with the NEC's safety requirements. Exposed wiring can lead to injury or damage, unrestrained wiring does not adhere to safety principles, and underground installation alone does not account for the specific challenges posed by wet locations.
