What type of installations is addressed by Article 680 of the NEC?

Article 680 of the National Electrical Code (NEC) specifically addresses the installation of electrical equipment in or near swimming pools, fountains, and similar installations. This includes the guidelines and requirements to ensure the safety of both the electrical systems and the people using these water-related facilities. The article emphasizes the importance of grounding, bonding, and proper installations to mitigate the risks of electric shock in environments where water and electricity coexist.

The NEC has dedicated this article to ensure that installations meet safety standards that take into consideration the unique hazards presented by water-related environments. This includes requirements for lighting, receptacles, and other electrical elements, to enhance safety and reduce the potential for electrical accidents.

Other options mentioned, such as emergency systems, solar photovoltaic systems, and temporary installations, are covered under different articles in the NEC and do not specifically address the safety and installation procedures for swimming pools and similar aquatic environments. Therefore, the emphasis on swimming pools, fountains, and similar installations under Article 680 is critical for safe and effective electrical installations in these contexts.
