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.
QUESTION: “What is the difference between the National Electrical Code (NEC) and the NEC Handbook (both published by NFPA)?”. The Handbook has the same content as the NEC book 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.
NOTICE: The questions we have designed for this exam do not include content from the two “index” books shown above. These titles are not code books. They are companion references to help exam takers find subjects in the NEC.
Questions are sourced from the National Electrical Code (NEC) and the 2017 version of Ugly‘s Electrical Reference.
The price of study materials varies and is based on the number of questions included in your files.
Questions can range anywhere from 2,170 questions, as in Master and Journeyman exams, to 140 questions as in TV Technician exam.
