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.
We 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. Most ICC exam locations will allow original, copyrighted copies as long as you don't add any of your own written notes.
