**Description:**
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 the residential construction industry! Training materials are now available for many of the residential crafts based on skill standards developed by the nation's leading builders and educators. The result of a strategic partnership between the National Association of Home Builder's Home Builders Institute and Delmar Learning, the Residential Construction Academy Series is the perfect way to teach essential workplace skills to people new to the building trades.
Ideal for use in vocational programs, workforce development programs, professional associations, and trade unions, all materials are based on industry standards. The Residential Construction Academy also offers credentialing for programs using the skill standards and materials, along with a national registry of students who have successfully completed participating programs. The goal is a workforce that is skilled, knowledgeable, and able to meet the needs of the industry today and well into the future. **Product Benefits:**
- examples are used extensively throughout the text to help students master the material
- a separate chapter on Safety emphasizes the importance of safety on the job
- a Glossary of Terms opens each chapter to give students easy access to terminology when they need it
- additional pedagogical features -chapter overviews, objectives, summary, practice problems, and review questions- support the text material
- an extensive full-color art and photo program brings the topic to life for students
