The authors explain each article in detail with thorough discussions, practical examples that illustrate how the Code® is applied, and sample Code® calculations taken from actual field applications. In addition, the authors integrate essential wiring information not directly addressed in the NEC®, but extremely useful to electricians on the job. This is a comprehensive, trusted resource you will reference time and time again throughout your career.
