Tab your code book before exam day, start every lookup from the index, and practice against a clock. Most journeyman electrician exams are open book with a time limit, so the skill that matters is finding the right section quickly, not memorizing it.
1. Check what your exam allows
Rules on tabs, highlighting and notes in the code book vary by state and testing provider. Read your candidate handbook first, so the book you practice with is the book they'll let you bring.
2. Tab the book before exam day
Tab the parts you'll reach for most, so you can open close to the answer and finish with the index. A common starting set:
- Article 100 (definitions)
- Articles 210 and 220 (branch circuits and load calculations)
- Articles 230 and 240 (services and overcurrent protection)
- Article 250 (grounding and bonding)
- Articles 300, 310 and 314 (wiring methods, conductors and ampacity tables, boxes)
- Article 430 (motors) and Article 450 (transformers)
- Chapter 9 tables and Annex C (conduit and tubing fill)
Use one color per group and keep the tabs readable from the edge. Some candidates add a tab for each table they use in calculations.
3. Use the index, not the table of contents
Pick the most specific word in the question ("receptacle", "bathroom", "ground-fault") and look it up in the index. It points to the section, and your tab gets you to the right part of the book quickly.
4. Practice against a clock
Divide your exam's time limit by its number of questions. That's your average time per question. Practice lookups until most take less than that, and skip anything that's eating your time. You can come back to it at the end.
5. For calculations, write the reference first
Before doing the math, note the section or table you're using. It keeps you from mixing up tables, and it lets you check your work quickly if time allows.
Timed lookup drills for your own tabbed code book, practice questions that cite the code section, and exams in your state's format.
