A class that provides the theory and background to understand motor control circuits and associated equipment. Course includes electrical theory, series circuits, parallel circuits, combination circuits, AC circuits ( sine wave, single phase, three phase, neutral conductor), transformer theory, ladder diagrams, wiring diagrams, troubleshooting control circuits, fuses, circuit protection, and testing fuses and circuit breakers.
The material is presented in a way that is easy to understand and gives you the ability to apply what you have learned.
There are demonstrations and hands-on exercises.
