Carol Fey's Quick and Basic Electricity is your guide to HVAC circuits, controls, and wiring diagrams. Within 80 quick pages, Carol manages to
explain electricity in a way that's not only understandable, but also
fun. At one point, she actually uses the example of two guys fishing for trout to
explain how a double-pole, double-throw switch works. This is they way to learn! Carol has worked in
the controls industry for more than many years. She was once named
National Technical Trainer of the Year by the American Society of
Training and Development, and she writes beautifully. Add a copy
of this book to your library. I will make you a better troubleshooter.
