Which NEC article covers general safety requirements for electrical installations, including enclosure integrity and workmanship?

• A. Article 110
• B. Article 200
• C. Article 230
• D. Article 210

Answer: (A)

The question tests understanding of where the NEC sets the overarching safety rules for electrical installations. The rules that govern general safety, including keeping enclosure integrity intact to protect against contact with live parts and setting expectations for proper workmanship and installation practices, form the foundation that ensures all installations are safe from the outset. This part of the NEC establishes the broad requirements for how installations should be performed, how equipment is installed, and how it is protected, so that everything works together safely.

Other parts of the NEC focus on different topics: definitions, service conductors and supply equipment, or branch-circuit requirements. Those areas address specific aspects or components, not the broad safety framework and workmanship standards that apply to all installations.
