The exam does not use the code book’s words

Open book means the answer is in front of you. It does not mean you can find it. This maps how questions are worded onto where the rule actually lives.

The real problem with an open-book exam

The 2026 edition rewrote how the chapters relate to each other, and the old rule about Chapter 8 is gone Chapters one through four apply generally to all electrical installations. Chapters five through eight may supplement or modify the requirements in chapters one through eight. Chapter nine is the tables, applicable as referenced. The informative annexes are not requirements. In earlier editions chapter eight stood apart and was not subject to the other chapters unless a requirement was specifically referenced in it. That carve out is not in the 2026 wording, and the chapter titles changed from special to specific at the same time. CHAPTERS 1–4 apply generally to all electrical installations may supplement or modify chapters 1 through 8 CHAPTERS 5 – 8 specific occupancies and locations · specific equipment specific conditions and systems · communications systems CHAPTER 9 tables, applicable as referenced ANNEXES A – L not part of the requirements CHANGED IN 2026: chapter 8 used to stand outside this stack. it was not subject to the other chapters unless something in it said so. that carve out is gone, and the chapter titles say specific now, not special.
Deciding which layer a question lives in is most of the work on an open book exam. In 2026 the layers themselves changed. Quoting the arrangement described in NEC 90.3, 2026 edition. Compare it with the edition on your own bench.

6,181 of 26,303 attempts passed a Texas electrical examination in fiscal 2025, so roughly three in four did not, and every one of those candidates had the book open in front of them.

You are not being tested on whether you know the rule. You are being tested on whether you can find it, repeatedly, at the pace the clock sets. The journeyman knowledge portion allows 130 minutes for 59 items and the calculations portion 110 minutes for 26, which works out at 2.2 and 4.2 minutes an item, counting the unscored pretest items you sit without being able to tell them apart.

And the exam does not phrase questions the way the code phrases rules. It uses trade language. The code uses defined terms. The gap between those two vocabularies is where the clock runs out.

How to use what follows

This is a translation table, not a study guide. It takes the words a question is likely to use and tells you which article to turn to.

Build your tabs from it. Not from the table of contents, which is organized the way the code thinks, but from this, which is organized the way questions are asked.

Nothing here reproduces code content. It points. You still read the rule in your own book, which is the only place it should be read.

If the question says it is about wire size

Derating and termination are two different limits and a question can turn on either. When both apply you take the more restrictive result, and questions are built to make you stop after the first one.

If the question says it is about a raceway or a box

Chapter 9 is at the back and it is easy to lose. Tab all three tables plus Annex C. That is four tabs that pay for themselves in the first hour.

If the question says it is about a motor

Figure 430.1 at the front of the article is a map of which part answers which question. It is the fastest navigation aid in the whole code and most candidates never look at it.

If the question says it is about grounding

Article 250 is long and reads badly front to back. Tab by these subheadings rather than by part, because questions arrive by topic and not by the article’s own structure.

If the question says it is about loads or services

If your book still has a tab that says 220, move it before you travel rather than in the room.

If the question says it is about protection or devices

GFCI is the most-changed section across recent editions. If your study material is more than one cycle old, treat 210.8 as unknown and read it fresh.

A tab strategy that survives the clock

Tabs are allowed, but only permanent index tabs manufactured or provided by the code book publisher. The bulletin rules out homemade, do-it-yourself and non-NEC tabs by name, so plan around a purchased set rather than index flags.

  1. Tab the four Chapter 9 items first. They are the furthest from where the book naturally falls open.
  2. Tab Article 120, and physically remove or relabel any tab that says 220.
  3. Tab 310.15, 110.14, 240.4 and 240.6 individually rather than tabbing the whole article. Those four sections carry most of the sizing questions.
  4. Tab Figure 430.1 rather than the start of Article 430.
  5. Tab 250.24, 250.66 and Table 250.122 individually. Tabbing the front of Article 250 does not help.

Fewer, better-placed tabs beat a book with a tab on every article. A hundred tabs is the same as none.
