The most comprehensive book on this subject available! A virtual encyclopedia of electrical safety, this latest edition features a new structure. The author rewrote and re-ordered the chapters, either to better reflect today's perspective or to clarify the presentation. Magison expanded his treatment of theory and principles to provide a foundation for addressing some of the questions that arise when no standard or regulation exists. He also added more practical examples of applying principles in real situations. Recognizing the fact that the book's subject matter is truly an international concern, Magison increased the amount of space devoted to work outside North America.
