The sixth edition of Electrical Grounding has been thoroughly updated in accordance with the 2002 National Electrical Code (NEC�), including a major reorganization of sections in Chapter 3 of the NEC and increased use of metric measurements. Early chapters serve as an orientation to the "what" and "why" of grounding, including explanations of the electrical theory and terminology used in Article 250 of the NEC�. Subsequent chapters of the book permit readers to explore individual conductors used in the grounding system in detail, starting with the grounding electrode. Permitted materials (including metal, steel and encased concrete), installation, sizing, and potential pitfalls are addressed. Once readers have become comfortable with basic installations, the book devotes attention to special installations, such as: separately derived systems, multiple buildings or structures served by a common service, high-voltage installations, and the use of ground-fault protection. The author's unique systematic approach has served as an effective path to true understanding of every phase of electrical grounding for countless journeyman electricians.
