This course will focus on preparing students for success in the HVAC/R industry. Because of the many electrical drive motors, electrical controls and in general, the large amount of electrical type problems likely to be encountered, the technician needs to be skilled in diagnostics, circuit diagrams and electrical meter application. This course will prepare the student to that end. The student will be exposed to real circuits. Placing the volt, ohm, and amp meter test leads on the circuit to discover what troubleshooting clues the readings will indicate. Time will be spent creating circuits by reading schematic wiring diagrams. Participants will be creating wiring diagrams from looking at existing diagrams. Taking volt, ohm, and amperage readings for preventive maintenance will also be an activity in this class. Electrical simulators will be utilized by the students during the duration of the course. Prerequisites: REFG 121 and REFG 123. Corequisite: REFG 122. (S)
