ELEC 120 - Industrial Electricity and Maintenance

4 Credits: (3 lecture, 2 lab)

Course Description
The Industrial Electricity and Maintenance course deals with electrical control devices, motors and power systems and their applications in a typical modern manufacturing or processing environment. The topics covered provide the student with the knowledge and skills to understand how these systems work so that they can effectively maintain and troubleshoot them.

Prerequisite ELEC 101 or ELEC 110 or permission of instructor.
