REFG 122: Electrical Theory II

Credits 3
From motor theory to HVAC/R components to the wide varieties of electrical diagrams, the course focus is to give the student a strong background in electrical understanding necessary to install and service heating, ventilating, air conditioning and refrigeration systems. Special emphasis will be applied to troubleshooting techniques and skills. This course will provide an in-depth look at electric motor theory while examining electrical inductance and capacitance. Five motor types will be studied with an emphasis on their operation, selection and application as well as troubleshooting techniques. Motor starting dynamics and starting components will be studied as well. The course will also cover the wide variety of components and circuits that are likely to be encountered in the HVAC/R industry. Electrical circuits and diagrams will be studied in-depth. Prerequisites: REFG 121 and REFG 123 or equivalents. (S)
