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.

Additional Recommended Books

The books listed below are NOT allowed at the exam location

1a.
Ferm's Fast Finder Index, 2020, IAEI
Buy at Amazon
1b.
Tom Henry's Key Word Index, 2020, 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.
