Which article outlines general requirements and definitions for electrical work?

The correct choice is Article 90, which outlines the general requirements and definitions for electrical work. This article serves as the introduction to the National Electrical Code (NEC) and is crucial for understanding the overall framework and purpose of the code. It not only defines key terms used throughout the code but also provides information on its applicability and the intent behind these regulations.

Article 90 is essential for electricians and other professionals in the field because it establishes a foundational understanding of how the subsequent articles are organized and applied. This understanding ensures compliance with safety standards and helps in the interpretation of the entire code.

While other articles like Article 100 and Article 110 also contain important definitions and requirements, Article 100 specifically focuses on definitions of terms used in the code, and Article 110 addresses requirements for installation and general practices for safe and effective electrical work, but not the general framework itself. Article 250 deals specifically with grounding and bonding, which is a more specialized aspect of electrical work. Thus, Article 90 is the appropriate reference for general requirements and foundational definitions.
