About the Product

Packed with real-world examples, vivid illustrations, and the latest developments from the field, ELECTRICAL STUDIES FOR TRADES, 5th EDITION is ideal for current and future service technicians in air conditioning and refrigeration, construction, and facilities management--and anyone else who needs a practical knowledge of electricity. This reader-friendly book begins with an overview of basic electricity concepts rather than introducing complex mathematical calculations. From this starting point, readers proceed directly to "must-know" information, including how to determine wire sizes and make a variety of common switch connections. Different types of electrical power panels are also examined in detail. Discussion of general wiring practices and circuit protectors, as well as an introduction to transformers and three-phase and single-phase motors, round out the comprehensive coverage.


  • Up-to-date photographs and illustrations throughout the text give students valuable insight into chapter concepts.

  • The Fifth Edition includes the latest information available on grounding and procedures for testing the quality of the grounding system.

  • The text explains in detail the procedure for determining conductor size, fuse or circuit breaker size, overload size, and starter size for electric motors.

  • The thorough section on General Wiring Practices includes information on low voltage chime circuits.

  • Helping instructors maximize their teaching time, engaging PowerPoint presentations of the units as well as comprehensive test banks are now available on an instructor companion website.

  • Providing the latest information on both motion and process control, the text offers thorough coverage of industrial control.

  • A wealth of examples mirroring the types of situations technicians face in the field are included throughout to reinforce the practical, applied approach to electricity fundamentals.

  • Measurement instruments commonly used in the field are identified and explained to help readers effectively use them and interpret results.

  • Unique stand-alone units allow readers to gain an overall understanding of electricity basics, while focusing their attention on topics that relate to particular trades.
