QUESTION:  "What is the difference between the National Electrical Code (NEC) and the Handbook version?".  As far as the actual NEC code quoted in the text... it's the same.

The NEC Handbook has additional diagrams, graphics and explanations inserted into the text (adding more pages and raising the price).  It was designed for engineers and inspectors.  The typical exam candidate should not use it as a preferred reference.

The study materials we are offering for this exam will exclude questions from reference #3 book which is not used by any other jurisdiction and is an out-of-print version.

Additional Recommended Books

The books listed below are NOT allowed at the exam location

Ferm's Fast Finder Index, 2023, IAEI
Buy at Amazon
Tom Henry's Key Word Index, 2023, Tom Henry
Buy at Amazon

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.

Practical Calculations for Electricians, 2023, Ray Holder
Buy at Amazon
