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.

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.

Buy at Amazon

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.  The "Basic Knowledge" covered in the exam is assumed and sometimes not listed as a subject. This book also covers subjects listed as "Calculations and Theory".
