Part of the Residential Construction Academy series, Electrical Principles bridges the gap between theory books that include topics that electricians do not need to know (e.g., resonance and devices) and books for electricians that try to cover all the theory in one chapter. Instead, through the use of a lively writing style and frequent examples, Stephen Herman expands on the important topics that residential electricians need, so that students have time to fully grasp the concepts they?ll need on the job. This text focuses on the theory that a residential wireman needs and it includes important safety and OSHA information. Create a direct link between your education/training program and…
