ELEC-138 Control Panel BuildingCredits 3 / 4 Contact Hours
Pre-requisite: Placement into RDNG-016 (ACSR-016); ELEC-131. NOTE: Student must provide own safety glasses.
This course examines the design and construction of electrical control panels as used in modern industrial automation systems. The student will participate in the design process of an automated control panel including all support documentation, cable fabrication, assembly, and test. The learning plan is aimed at entry level technicians who are involved in the design, assembly, test, startup, troubleshooting, maintenance, repair, and upgrade of automated systems.
