What does Article 200 cover?

• A. Use and identification of conductors, including color coding and identification rules
• B. Overcurrent protection requirements
• C. Wiring methods
• D. Service grounding

Answer: (A)

Article 200 governs how conductors are used and identified in electrical installations, including the color coding and labeling that show a conductor’s function. This sets the rules for which colors or markings indicate hot conductors, neutrals, and grounding conductors, and it covers how conductors must be identified in terminations, cable assemblies, and raceways. For example, hot conductors are typically colored black, red, or blue; the grounded (neutral) conductor is white or gray; and the grounding conductor is green or bare. These identification rules help ensure safety and clarity when servicing or modifying circuits. This topic is distinct from overcurrent protection (covered elsewhere), wiring methods, or service grounding, which is why the correct choice focuses on use and identification of conductors.
