Where is the index located in your code book?

• A. The front of the NEC
• B. The back of the NEC
• C. The middle of the NEC
• D. The inside cover of the NEC

Answer: (B)

The index is placed at the back of the NEC because it serves as a comprehensive lookup tool that cross-references topics, terms, and article numbers across the entire code. After you’ve reviewed the table of contents to see what’s inside and studied the articles for context, the back-of-book index lets you quickly find where a topic is discussed and the exact pages to turn to. This front-to-back structure is a standard design for large reference manuals, making navigation efficient: front for overview and contents, middle for the main material, and back for the index. The inside cover is usually used for quick info or publication details, not a full index. So the back of the NEC is the natural location for the index.
