BULLETIN ERRORS: In the bulletin dated 9/1/24, you will find that the numbering for subcategories in the content table are completely wrong. Also, the title for item #7 should not be "Special Communications". We have corrected the title above.
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 questions are sourced from the National Electrical Code (NEC) and Ugly's Electrical References. We include questions from three versions of Ugly's.
A subject category index mapped to question numbers is included with the answer key.
The approximate number of sample questions in this package is 2,475.
