McGraw-Hill's NEC 2014 Grounding and Earthing Handbook

if you are responsible for delivering power, or if you just want to know whats 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 stockins 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-Hills 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 Codes 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.
