Which article of the NEC covers definitions?

• A. Article 100
• B. Article 430
• C. Article 200
• D. Article 310

Answer: (A)

Definitions are provided in the article that is dedicated to Definitions. This article acts as the code’s glossary, giving the standard meanings for terms like grounded conductor, neutral, equipment grounding conductor, and many others so that every rule in the NEC is interpreted consistently. That consistency is crucial because the code addresses safety-critical requirements and relies on precise terminology. The other articles focus on specific topics—how to identify conductors, conductor properties and ampacity, or motors and controllers—so they rely on the terms defined in this definitions article rather than defining them anew.
