NOTICE: If your PSI exam bulletin shows the 16th Edition (out-of-print version) of the American Electricians' Handbook, it has not been updated to show the current the 17th edition.
QUESTION: “What is the difference between the National Electrical Code (NEC) and the NEC Handbook?”. The Handbook has the same content as the NEC with additional drawings and explainations inserted.
The Handbook was designed for engineers and inspectors. The typical exam candidate should not use it as a prefered reference unless they are using it for inspection jobs in their day-to-day work.
We highly 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 questions are based on the PSI publication titled “29 CFR PART 1926 Selections, as of June 2013” (highlighted in green above).
This file contains approx. 800 sample questions.
REMINDER: PSI uses this book for many exams they offer. Not all sections of this code will apply to your exam.
