What types of electrical equipment are covered under NEC Article 680?

NEC Article 680 specifically addresses the electrical requirements for installations related to swimming pools, fountains, hot tubs, spas, and similar areas. This article is focused on ensuring safety and preventing electrical hazards in areas where the risk of electric shock is increased due to the presence of water.

Option B is the correct choice because it directly pertains to electrical equipment installed in and around pools, which includes wiring methods, grounding, bonding, and specific installation practices necessary to protect both users and maintenance personnel.

Other options do not align with the scope of NEC Article 680. Equipment used only for heating, general household electrical appliances, and exclusively lighting fixtures do not feature the specific safety considerations that are critically outlined in this particular article. The inclusion of water-related factors in B emphasizes the unique and hazardous nature of working with electrical equipment in wet locations, which is the primary concern of NEC Article 680.
