What references the California exam provides
This one rule changes how you should prepare. You do not bring a book you tabbed for months. You use what the center gives you. Speed in that book is the skill.
Last reviewed June 2026
What is provided
- NFPA 70, National Electrical Code, 2023 Edition
- NFPA 70E, Standard for Electrical Safety in the Workplace, 2024 Edition
- CAL/OSHA Pocket Guide for the Construction Industry, updated 2022
What you cannot bring
Your own tabbed code book, your own notes, or any personal reference material. The center provides the references, and that is what you use.
Why this decides the exam
When everyone has the same book and the same clock, the candidate who finds the rule fastest wins. That is why provided-reference speed, knowing the index and the rule families cold, matters more than memorizing answers.
