NOTICE: The Amazon link in the bulletin dated 5/26/23 goes to the wrong version of the NEC.
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.
The study materials we offer for this exam will cover the two non-NEC specific subjects (Electrical Theory and Calculations) with questions from Ugly's Electrical Reference.
Sample exam questions are sourced from the National Electrical Code (NEC) and Ugly's Reference (2017). 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.
The approximate number of sample questions in this package is 1,950.
