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.
Questions are sourced from the NEC and Ugly's Electrical References.
This package contains approx. 750 sample questions.
