The sixth edition of Electrical Grounding has been thoroughly updated in accordance with the 2002 National Electrical Code (NEC®) and now incorporates the use of metric measurements in addition to the foot-pound system. 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.

Features and Benefits

  • Whenever the same rule is applicable to more than one conductor, it is repeated when that conductor is discussed eliminating the distraction created by "back-and-forth" rule referencing.
  • Simplified line drawings and flow diagrams throughout the book offer guidance in calculating conductor sizes and reading NEC® tables.
  • Specific examples show readers how to calculate a conductor size, as well as how to use various NEC® tables (reproduced in the book) for grounding conductor sizing.
  • Comprehensive coverage of neutral (grounded) conductors spans the spectrum, from the use of grounded conductor connections in DC and AC systems through overcurrent protection.
  • Bonding on the line side of the service, as well as the load side of the service, includes discussion of various installations and sizing, as well as the reason for bonding jumpers.

Ronald O'Riley

After serving for fours years as an electrician's mate in the US Navy during World War II, and then serving a four-year electrical apprenticeship, Ronald P. O'Reily rose through the ranks on the job to become an electrical superintendent. In the process he has accumulated over forty years of experience in the electrical industry. During the past thirty-five years he has been an instructor of electrical theory and Code classes for electrical apprentices and journeyman training, serving for many od those years as the training director of the Dallas JATC. He is a retired member of the International Brotherhood of Electrical Workers and an active associate member of the IAEI, where he has served for several years as an officer of the Texas Chapter.
