Product Details

Electricity is a very large part of an HVAC technician’s day-to-day experience. Almost every system failure involves one or more electrical components in the equipment being serviced. An HVAC technician must be fluent in line and low voltage electrical circuits. In fact, much of a technician’s reputation has to do with how well-versed he is in low voltage circuitry.

This book will cover conductors and insulators, basic principles, transformers, series and parallel circuits, relays, contactors motors, Ohm’s Law, voltmeter, ohmmeter, flame rectification, wiring diagrams, thermostats, compressors, capacitors, impedance relays, line voltage, hydronic systems, thermocouples, electrical safety and more.
