What type of installations are detailed in Article 680?

Article 680 of the National Electrical Code (NEC) specifically addresses the requirements for electrical installations related to swimming pools, fountains, and similar installations. This article encompasses a wide range of outdoor water features that require special considerations for electrical safety, primarily due to the inherent hazards associated with water and electricity. The NEC establishes guidelines for wiring methods, equipment, grounding, and bonding specific to these types of installations to mitigate risks such as electric shock or equipment failure.

Various aspects covered in Article 680 include installation practices for pool lights, underwater equipment, and the necessary clearances and barriers to protect users. It also outlines the specifications for GFCI (Ground Fault Circuit Interrupter) protection, which is crucial for ensuring safety in wet environments. Consequently, this focus on safety in locations with potential electrical hazards is why the correct answer pertains to swimming pools, fountains, and installations that share similar environmental conditions. The other options listed do not fit under Article 680's scope, which centers specifically around these aquatic features and their electrical requirements.
