Question
Chapter 30, Problem 1R
To determine
Mention the NEC article number which is used to cover for the wiring of swimming pools.
Expert Solution & Answer
Answer to Problem 1R
The NEC Article 680 covers for the wiring of swimming pools.
Explanation of Solution
Discussion:
Refer to NEC Article 680 which states that the article contains a special requirement that is unique to all swimming pools, decorative pools, wading pools, fountains, spas, hot tubs, therapeutic, and similar water-related equipment’s. Therefore, the requirements for the wiring of swimming pools are in addition to the general Code requirements and are also found in other articles of the NEC.
Conclusion:
Thus, the NEC Article 680 covers for the wiring of swimming pools.
