Which articles in the NEC® contain requirements for GFCI protection of receptacles?

• A. Article 555
• B. Article 680
• C. Article 620
• D. All of these

Answer: (D)

The correct answer encompasses the fact that GFCI (Ground Fault Circuit Interrupter) protection requirements for receptacles are addressed in multiple articles of the NEC (National Electrical Code). Specifically, Article 555 deals with marinas, boatyards, and similar locations, which necessitate GFCI protection for receptacles used in wet environments, where the risk of ground faults is heightened. Article 680 addresses swimming pools, spas, hot tubs, and similar installations, setting requirements for GFCI protection to ensure safety in areas where moisture and electricity converge. Lastly, Article 620 pertains to elevators, escalators, and moving walkways, also specifying conditions under which GFCI protection might be necessary for receptacles in these applications as part of safety considerations. By acknowledging that GFCI protection is vital in various environments with significant risk factors, the NEC ensures safer electrical installations across different settings, making it appropriate to state that all these articles collectively contribute to GFCI requirements. Thus, recognizing the interrelatedness of safety regulations across all of these contexts justifies the answer that all of these articles contain GFCI protection requirements for receptacles.
