Based on national standards set by the residential construction industry, the new Residential Construction Academy Series is the result of a partnership between Home Builders Institute and Delmar Learning. This series is the perfect way to guide learners to development of essential workplace skills. Electrical Principles focuses on the important topics that residential electricians need, presented logically so that learners can fully grasp the concepts they will need on the job. This book covers each of the work functions, key activities, and specialties addressed in the NAHB's Residential Electrician Skill Standards. Through the use of a lively writing style and frequent examples, Stephen Herman provides a blend of practical and theoretical material that is easy to follow. This book focuses on the theory needed by a residential wireman, including Ohm's Law, circuits, instruments, direct and alternative current theory, transformers, motors, important safety information, and more.
