HET 250 - Intermediate AC and DC Circuits

This course covers intermediate AC and DC circuitry, the laws of electricity, wiring of HVACR equipment, and safety procedures with an emphasis placed on sustainable energy sources. Through lectures, demonstrations, and lab experiences, students will learn about various types of residential and commercial heating and air-conditioning, commercial refrigeration electrical service, and installation and preventive maintenance techniques. The function and operational characteristics of various types of electric controls will be covered including thermostats, defrost controls, relays, contactors, capacitors, power distribution, motors, system malfunction diagnosis, corrective procedures, and protective devices. This course also introduces part-winding starts, Wye and Delta wound transformers, programmable controllers, Electronically Commutated Motors (ECM), and Variable Frequency Drive motors (VFD). The National Electrical Code is reinforced, as well as the use of meters, schematics, wiring diagrams, electrical troubleshooting, electrical service procedures, and electrical test equipment. Please note that all course materials and content are provided in the IMS Common Cartridge (IMSCC) format. The content can be accessed by opening the IMSCC file using your organization's Learning Management System application (these include Blackboard, D2L, Canvas etc.). Additional information about accessing Common Cartridge files can be found on the IMS Global Web site: http://www.imsglobal.org/cc.
