Department Overview
 Department Name: Electrical Systems Department Number of Classes: 15

Department Description
Possibly the most important source of power that we rely on is electricity. Electricity powers our computers, drives the machines tools in a manufacturing shop, and lights the facility. To maintain all this electrical equipment, employees must understand the fundamentals of electricity and the components used to generate, control, and store it.

These classes explain the key concepts of electrical maintenance for individuals in the manufacturing environment. The class content first addresses the main principles, units of measurement, and components used in simple electrical circuits. Intermediate-level classes address methods for calculating electrical units, the principles of alternating current, and specific comparisons regarding the selection of electrical components.
