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 book above contains practical applications of the NEC such as Ohm‘s Law, series/parallel circuits, voltage drop, load calculations, motor phases, impediance, inductance and math formulas you are expected to know. “Basic Knowledge” and “Electrical Calculations” are subjects covered in the exam and are assumed (most likely not listed as a subject for electrical and mechanical exams of all types).
Sample exam 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.
