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.
Sample questions are sourced from the National Electrical Code (NEC) and Ugly's Reference. 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.
Additional bonus sample calculations for Ohm's Law and Series/Parallel combination circuits are included.
Questions have been upgraded to the new exam content published by ICC on 11/30/21.
The total number of questions in this package: 2,041
