The official exam bulletin is published and maintained by PSI. Bulletin content (subjects covered in the exam) and file names for PDFs change regularly. Always set your “favorite” or “bookmark” to the landing page we have linked above. Candidates should always review the current exam information on the PSI website before applying or testing.
The books listed below may be allowed at the exam location as long as they have the original binding and no written notes. Read your exam bulletin and look for the "What to bring" or "What is allowed" statement for specific restrictions.
We recommend that you purchase one of the reference books above to study for your exam. Each book is a comprehensive subject index to the NEC. They provide an even faster way to look up answers in the code and are far more detailed than the index at the end of the code book.
Sample exam questions are sourced from the 2023 version of the National Electrical Code (NEC) and Ugly's Electrical References (2020 & 2023 versions).
This package contains approx. 2,570 sample questions.
Additional bonus sample calculations for Ohm's Law and Series/Parallel combination circuits are included.
