A companion to the text HVACR Troubleshooting Fundamentals Electricity and Wiring Diagrams

With the majority of HVACR service calls being electrical in nature, it is important for technicians to have a solid understanding of electrical fundamentals allowing them to develop a systematic and methodical approach to troubleshooting. Electrical Theory and Application for HVACR provides students and practicing technicians with the information and knowledge necessary to accurately and safely diagnose and solve electrical system faults. Electrical Theory and Application for HVACR was written by HVACR instructors for HVACR instructors to simplify the instruction of electricity. The manual is full of color illustrations and includes worksheets that provide students and practicing technicians with the information and knowledge necessary to accurately and safely diagnose and solve electrical system faults. Main topics include: safety and hazard awareness, electrical fundamentals, motors, circuits and components, wiring diagrams, automated control systems, and troubleshooting. The spiral binding will allow students to tear out worksheets for grading by the instructor.

This book provides HVAC/R service technicians with exceptionally practical information on the unique wiring diagrams, methods, technician short-cuts, and potential pitfalls encountered on the job. It begins with a discussion of general electricity and electrical circuits, and then moves quickly into explaining wiring diagrams for HVAC and refrigeration systems, and the new devices that are encountered with each new diagram. It features accessible, technician-level explanations of electronics. Electrical Concepts. Simple Currents. Standing Pilot Furnaces. Heating/Air Conditioning Circuits. Troubleshooting Strategies.
