Summary

Extraordinarily comprehensive, this book is completely updated to the 2005 National Electrical Code. and continues to offer valuable insight into the Code. articles. Explanations are provided for each article in detail, with thorough discussions and practical examples that clearly illustrate how the Code. and its most recent changes are applied. Discussions are logically organized into coherent subject groupings, allowing readers to navigate easily through 2005 NEC. requirements as well as changes since the last edition. Through this approach, the book also integrates essential information into the 7th Edition that is not directly addressed in the NEC but is extremely useful to electricians.
