Which article provides definitions relevant to electrical terms?

Article 100 is the section of the National Electrical Code (NEC) that focuses specifically on definitions and terminology used throughout the code. This article establishes the meaning of various electrical terms, which helps in understanding the context of the regulations provided in the subsequent articles. By having a dedicated section for definitions, it ensures that all users of the code, including electricians, engineers, and inspectors, have a clear and common understanding of the terminology, which is essential for ensuring safety and compliance in electrical installations.

This foundational knowledge is critical because proper interpretation of the code rests on the accurate comprehension of terms. For instance, definitions of terms such as "ground," "circuit," and "feeder" set the stage for the rules detailed in other articles, which govern the installation and maintenance of electrical systems. Therefore, understanding Article 100 is essential for anyone working with electrical codes.
