| Chapter | Think of it as |
|---|---|
| 1 | General |
| 2 | Wiring and protection |
| 3 | Wiring methods and materials |
| 4 | Equipment for general use |
| 5 | Special occupancies |
| 6 | Special equipment |
| 7 | Special conditions |
| 8 | Communications systems |
| 9 | Tables |
Start with the question, identify the equipment or system, predict the relevant chapter or article, then confirm definitions and exceptions. Do not stop at the first sentence that appears to answer the question.
