Which NEC article covers the general safety requirements for electrical installations?

• A. Article 110 (General safety)
• B. Article 500 (Hazardous locations)
• C. Article 410 (Luminaire mounting)
• D. Article 392 (Cable trays)

Answer: (A)

The general safety requirements for electrical installations are found in the NEC article titled General Requirements for Electrical Installations. This article sets the overarching safety rules that apply to nearly all electrical work, covering things like acceptable enclosure types, required working space around equipment, proper insulation and protection of conductors, and safe workmanship practices. The other articles address specific areas: hazardous locations (Article 500) deals with installations in potentially explosive environments, luminaire mounting (Article 410) focuses on lighting fixtures, and cable trays (Article 392) covers the use of cable tray systems. So the best answer points to the article that governs broad safety rules across installations rather than a specialized topic.
