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.
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.
Reference #2 above contains practical applications of the NEC such as Ohm‘s Law, series/parallel circuits, voltage drop, load calculations, motor phases, impedance, inductance and math formulas you are expected to know. “Basic Knowledge” is covered in the exam but detailed subjects are assumed and not specifically called out in the bulletin.
A "calculations" book where you can drill yourself repeatedly is always a good way to remember the most basic math procedures. Generally, you won't have time during an exam to search for these procedures in a book.
Sample exam questions are sourced from the National Electrical Code (NEC) and the 2020 & 2023 versions Ugly's References. A subject category index mapped to question numbers is included with the answer key.
Bookmarks have been added to help the user randomly jump to specific questions related to NEC Articles in the code.
Total number of questions in this package: 1,325
