About the Book
For anyone who has ever experienced the challenges of deciphering and applying the more difficult sections of the 2008 NEC(R): Understanding and Applying the 2008 NEC offers fresh, easy to understand interpretations of the most challenging and commonly misunderstood sections of the NEC(R). The author uses his 40+ years of experience to deliver a straightforward approach that eliminates the confusing technical and legal jargon of the code. Coverage begins by providing a tour of the NEC(R), explaining its overall layout. It then progresses to how the electrical parameters of the other codes, such as building, fire,and utility codes, play a role in proper electrical installations. Perfect as an on-the-job reference to guide readers through easy, accurate installations; this is a comprehensive resource that will benefit aspiring and professional architects, engineers, electricians, inspectors, and anyone working in the electrical field
