Parts and articles in the NEC are further divided into numbered what?

In the National Electrical Code (NEC), the organization of the code is structured in a highly systematic manner to provide clarity and ease of reference for users. Parts and articles are further divided into numbered sections. This division allows for a clear hierarchy in the document, making it straightforward to locate specific rules and requirements related to electrical installations and safety.

By using sections, the NEC facilitates effective communication of electrical standards, as each section encompasses distinct topics or principles. For instance, each section may focus on different aspects of electrical systems, such as wiring methods, grounding, or safety practices. The numbering system enhances this organization, allowing electricians, inspectors, and other stakeholders to quickly and accurately reference the applicable rules.

Other terms mentioned in the answer choices do not align with the formal structure of the NEC. The use of sections contributes significantly to the overall functionality and usability of the code.
