Electrician School Year 1 2025 – 400 Free Practice Questions to Pass the Exam

The correct answer is found in Article 100 of the National Electrical Code (NEC), which specifically contains definitions for terms used throughout the code. This article serves as a comprehensive glossary to ensure clarity and a common understanding of the terminology necessary for interpreting and applying the code effectively. Definitions in this section help electricians understand the various terms used in the NEC, which is essential for safe and compliant electrical installations.

Article 90, while focused on the purpose and scope of the code, does not provide specific definitions. Article 200 pertains to wiring methods and conductors, while Article 300 addresses general requirements for wiring methods, but neither of these articles contains the foundational definitions that are systematically grouped in Article 100. By familiarizing oneself with Article 100, an electrician can navigate the code more effectively and ensure proper application of its requirements.
