"If you are responsible for delivering power, or if you just want to know what's going on beneath your feet, read these pages; ground your circuit as Stockin suggests, and you can close the master switch with confidence." ―Bill Nye, "The Science Guy"
"David Stockin's book develops a clear understanding of Code requirements through extensive use of illustrations and clear text." ―David Brender, P.E., Code-Making Panel NO. 5 member
"Stockin adds his own experiences to the fundamentals of NEC 250, allowing readers to visualize practical applications of routine rules in a new and novel way." ―Travis Lindsey
McGraw-Hill's National Electrical Code 2014 Grounding and Earthing Handbook fully addresses the above-grade grounding and below-grade earthing issues related to Article 250 of the 2014 National Electrical Code. This practical guide features in-depth discussions of each of the Code's requirements, section by section, along with clear explanations and real-world examples.
For ease of reference, a separate chapter calls out all of the changes introduced to Article 250 of the 2014 NEC. Information on the Canadian Electrical Code is also provided. A helpful question-and-answer chapter covers common on-the-job topics, and more than 100 detailed diagrams illustrate the information presented in this authoritative resource.
