Which code article pertains to definitions?

• A. Article 100
• B. Article 200
• C. Article 300
• D. Article 400

Answer: (A)

Definitions are provided in a dedicated article of the NEC to establish exact meanings used throughout the code. This article sets the definitions for terms like conductor, grounded conductor, equipment grounding conductor, service, branch circuit, and many others, so everyone reads and applies the rules with a common vocabulary. Because all other articles rely on these defined terms to interpret requirements consistently, this article is the one you consult for meanings of terms rather than for specific wiring or protection rules. Other articles cover topics such as conductors, overcurrent protection, wiring methods, and grounding, but they assume you understand the defined terms from the Definitions article.
