Residential Construction Academy Electrical Principles 2nd Edition by Stephe N L. Herma N | PDF Free Download.
The shortage of skilled labor is one of the most pressing problems confronting the building industry today. The construction industry must recruit an estimated 200,000 to 250,000 new craft workers each year to meet future needs.
This shortage is expected to continue well into the next decade because of projected job growth and a decline in the number of available workers.
At the same time, the training of available labor is becoming an increasing concern throughout the country. The lack of training opportunities has resulted in a shortage of 65,000 to 80,000 skilled workers per year.
This challenge is affecting all of the construction trades, and it is threatening the ability of builders to construct quality homes. These challenges led to the creation of the innovative Residential Construction Academy Series.
The Residential Construction Academy Series is the perfect way to introduce people of all ages to the building trades while guiding them in the development of essential workplace skills, including carpentry; electrical wiring; heating, ventilating, and air conditioning (HVAC); plumbing; masonry; and facilities maintenance.
The products and services offered through the Residential Construction Academy are the results of cooperative planning and rigorous joint efforts between industry and education.
The program was originally conceived by the National Association of Home Builders (NAHB)—the premier association of more than 200,000 member groups in the residential construction industry and its workforce development arm, the Home Builders Institute (HBI).
For the first time, construction professionals and educators have created national skills standards for the construction trades.
In the summer of 2001, NAHB, through the HBI, began the process of developing residential craft standards in six trades: carpentry, electrical wiring, HVAC, plumbing, masonry, and facilities maintenance.
Groups of employers from across the country met with an independent research and measurement organization to begin the development of new craft training standards.
Care was taken to assure representation of builders and remodelers, residential and light commercial, custom single-family builders, and high-production or volume builders.
The guidelines from the National Skills Standards Board were followed in developing the new standards. In addition, the process met or exceeded American Psychological Association standards for occupational credentialing.
Next, through a partnership between HBI and Cengage/Delmar Learning, learning materials—textbooks, videos, and instructor’s curriculum, and teaching tools—were created to teach these standards effectively.
A foundational tenet of this series is that students learn by doing. To that end, integrated into this colorful, highly illustrated text are Procedure sections designed to help students apply information through the hands-on, active application.
The constant focus of the Residential Construction Academy Series is twofold: teaching the skills students need in order to be successful in the construction industry and constantly applying the learning to real-world applications.
The newest programming component to the Residential Construction Academy Series is industry Program Credentialing and Certification for both instructors and students by the Home Builders Institute.
National Instructor Certification ensures consistency in instructor teaching/training methodologies and knowledge competency when teaching to the industry’s national skills standards.
Student Certification is offered for each trade area of the Residential Construction Academy Series in the form of rigorous testing. Student Certification is tied to a national database that will provide an opportunity for easy access for potential employers to verify skills and competencies.
Instructor and Student Certification serve the basis for Program Credentialing offered by HBI. For more information on HBI Program Credentialing and Instructor and Student Certification, please go to www.hbi.org/certification.
Electrical Principles Second Edition is intended to present the concepts of electricity to learners interested in the field of residential wiring. It assumes that the learner has no knowledge of electricity and presents the subject in a very practical, straightforward manner.
The book begins with electrical safety and progresses through basic electrical theory; electrical quantities and Ohm’s Law; series, parallel, and combination circuits; measuring instruments; wire tables; magnetic induction; alternating current; transformers; and motors.
All mathematical calculations are explained in step-by-step detail. This book is an excellent choice for anyone entering the electrical field. Electrical Principles Second Edition is a blend of practical and theoretical.
The text not only explains the different concepts relating to electrical theory, but it also provides practical examples of how to do many of the common tasks the electrician must perform.
It was the author’s intention to make this book one that an electrician would want to keep in his toolbox for a reference. Although the text covers many areas of both direct and alternating current theory, the math level has been kept to basic algebra and basic trigonometry.
The subject matter for Electrical Principles Second Edition has been divided into separate stand-alone chapters.
Although the chapters have been divided in a logical progression, the stand-alone concept permits the information to be presented in almost any sequence the instructor desires.
In addition, the student or electrician does not have to search the entire text to find information concerning a particular subject; it is located within a certain chapter.
The second edition of Electrical Principles continues to blend practical and theoretical approaches to teaching electrical theory concepts.
This edition offers even more emphasis on the application of those concepts. New features include:
