The most popular electricians' handbook for the past 95 years has been updated the latest NEC and NESC rules and standards. This Handbook provides new coverage of autotransformers, LED and induction lighting, industrial control panels, high-impedance grounding and farm distribution systems, net-present-value calculations, and more. It also includes a systematic procedure for making cable pulls of any size or distance. Providing all the critical information needed to design, maintain, and operate systems and equipment, this fifteenth edition is the key to tackling even the most complex jobs with complete confidence. Focusing on systems and equipment rather than codes and calculations, this one-step resource is the most practical, hands-on guide available.
