NOTE: The study material we are offering for this exam will exclude sample questions for “Major Load Calculations” and/or “General Trade Knowledge” because they can not be created from code books or statutes. Those exam questions are proprietary, copyrighted inventions of PSI.
We highly recommend that you purchase one of the two NEC index 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 subjects covered in the exam and are far more detailed than the index at the end of the code book.
The price of the study materials varies and is based on your exam sub-category chosen in our order form on the next page.
Questions are sourced from the NEC and Washington statutes shown above. The files you will receive contain between 600 and 2,000 sample exam questions depending on the NEC sections required for your exam by PSI.
An answer key with detailed code sub-section references is included.
Additional bonus questions (60) are included from Ugly's Electrical Reference and American Electricians‘ Handbook.
