What is the purpose of Article 110?

• A. Specific grounding electrode requirements
• B. General requirements for electrical installations, including safety, enclosure integrity, and proper workmanship
• C. Color coding and identification of conductors
• D. Minimum overcurrent protection requirements

Answer: (B)

Article 110 outlines the general rules that apply to electrical installations. It isn’t about a specific device or topic; it sets the baseline for safe design, proper installation, and quality workmanship. It requires equipment to be listed and installed according to the manufacturer’s instructions, work to be performed to acceptable standards, enclosures to be protected and accessible, and adequate working clearances to be maintained. It also emphasizes using listed and labeled equipment and ensuring the overall installation protects people and property from electrical hazards. Topics like grounding electrodes, conductor color coding, or minimum overcurrent protection are covered in other parts of the Code, not in this general installation article.
