Journeyman Electrician Code Book: NEC Guide
Your journeyman electrician code book is the National Electrical Code, NFPA 70, and the edition your exam tests almost certainly isn’t the newest one available. NFPA published the 2026 NEC, but most states haven’t caught up to it yet: Texas tests the 2023 NEC, and Washington and North Carolina both still test the 2020 NEC as of this writing. Buying the newest edition off the shelf is a common, avoidable mistake.
The code book itself is also the tool you’ll use during the exam in most states, since these are open-book tests. That makes two things worth getting right before test day: the correct edition, and your state’s specific rules for how you’re allowed to mark and tab it.
What edition of the NEC will I be tested on?
It depends entirely on your state, and the safest move is checking your board’s current candidate bulletin rather than assuming the newest NEC edition applies.
| State | NEC edition tested | Source |
|---|---|---|
| Texas | 2023 NEC | TDLR Candidate Information Bulletin |
| Florida | 2023 NEC (moving to 2026 NEC effective August 21, 2027) | DBPR reference list |
| North Carolina | 2020 NEC currently enforced (2023 NEC adopted, under legislative delay) | NCBEEC Exam Information Handbook |
| Washington | 2020 NEC | WA L&I electrical examination page |
North Carolina is the clearest example of why “adopted” and “tested” aren’t the same thing. The state’s Building Code Council adopted the 2023 NEC with amendments, but Session Law 2025-2 placed its effective date under an indefinite delay, so the 2020 NEC, effective since November 1, 2021, remains the code candidates are actually tested on, per the NC Office of State Fire Marshal. A state can adopt a new edition on paper years before it shows up on your exam.
NFPA itself is direct about this lag: “many states may enforce editions of the NEC that are not the most current,” and the NEC runs on a 3-year revision cycle, with the 2026 edition superseding 2023 and the next one due in late 2028, according to NFPA’s own overview of the code. Confirm your exact edition with your state board before you buy a book.
Is the journeyman exam open book, and what can I bring in?
Yes, in every state we checked, but what counts as an acceptable code book is specific and enforced.
Rules converge on the same core idea, permanent tabs only, no handwritten notes during the session, but the details differ. Texas requires NEC books be tabbed only with permanent index tabs made or provided by the code book’s own publisher, and bans writing, highlighting, underlining, or indexing your book during the exam session itself, though pre-exam marking is allowed, per TDLR’s bulletin. Washington allows permanent index tabs but explicitly bans removable tabs, handwritten notes, or sticky notes, and proctors physically check books for banned items, according to L&I’s exam page. Florida is stricter still: existing handwritten notes must be blacked or whited out completely, and only permanent tabs are allowed, per DBPR’s reference list. Bring a clean, correctly tabbed book. Don’t assume a book you marked up for a different state’s rules will pass inspection in yours.
How is the NEC organized?
Nine enforceable chapters plus informative annexes, and knowing the chapter map matters more than memorizing individual rules, since exam questions often just test whether you can find the right section fast.
The NEC’s chapters run: 1, General; 2, Wiring and Protection; 3, Wiring Methods and Materials; 4, Equipment for General Use; 5, Specific Occupancies and Locations; 6, Specific Equipment; 7, Specific Conditions and Systems; 8, Communications Systems; 9, Tables, followed by Informative Annexes A through L covering ampacity calculations, conduit fill tables, and worked examples, per NFPA’s product page for the code. Article 100 (Definitions) and Article 110 (General Requirements for Electrical Installations) sit at the front of Chapter 1 because nearly every other article leans on terms and baseline rules defined there. If you’re not fast at Article 100 and 110, you’re slower at everything downstream of them too.
How much does a code book cost, and when should I replace mine?
The current NFPA softbound 2026 NEC lists for $169, or $152.10 at the NFPA member price, and you should replace your book only when your specific exam’s tested edition actually changes, not on a fixed calendar.
Since states lag NFPA’s publication schedule by anywhere from one to several years (Florida isn’t moving to the 2026 NEC for its exam until August 21, 2027, more than a year after this article’s publish date), buying a brand-new edition the moment NFPA releases it can mean showing up with the wrong book for your state’s current exam. Check your board’s candidate bulletin for the exact edition required, buy that specific edition, and hold onto it until your state’s own bulletin updates.
Practice navigating your specific edition’s chapter structure inside the AmpExam practice quiz before test day, so the first time you’re hunting for an article under a clock isn’t during the actual exam.
If fast code navigation combined with the calculations that show up alongside it is what you’re weakest on, the AmpExam Journeyman Handbook walks through the articles that dominate most state exams and the five calculations that come up constantly, built to make navigation fast, not just familiar.
FAQ
What NEC edition should I study for the journeyman exam? It depends on your state. Texas and Florida currently test the 2023 NEC; Washington and North Carolina still test the 2020 NEC. Always confirm the exact edition on your state board’s current candidate bulletin before buying a code book.
Can I use any edition of the NEC code book during the exam? No. You need the specific edition your state’s exam references. Bringing an outdated or newer edition than what’s tested can mean answers that don’t match your book’s article numbering or content.
Is the journeyman electrician code book exam open book? Yes in every state checked, but rules on tabbing and marking are specific and enforced by proctors. Permanent tabs are typically allowed; handwritten notes and removable tabs typically are not. Confirm your exact state’s rules before test day.
How is the NEC code book organized?
