The principles of electromagnetic induction are discussed and applied to the operation of DC generators, single phase AC generation, three phase alternators, and alternative power sources. Wye and delta connections will be explained and students will solve equations to determine voltage, current, and power in branch circuits. Students will distinguish various properties of conductors including type, physical size, ampacity, resistance, reactance, insulation, and temperature rating. Load requirements for branch circuits will be analyzed and appropriate wire type and size will be selected for the application. Other topics discussed include power factor correction, conductor derating, conductor identification, wire color codes, termination requirements, and conduit fill requirements. Credit may be earned in either ET 132 or SKET 132 but not both.
Prerequisites: ET120, SKET120
