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 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.
Ugly's References contain 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).
