Description

ELT 123 Electrical Controls I
3 Credits (2 lecture 1 Lab 0 Shop)
4 Hrs/Wk (2 Hrs. Lecture 2 Hrs. Lab) *15 wks
This course is a study of the functioning of electrical devices that are primarily used for manual switching of circuits such as piloted single-pole switches, Eagle three-way switches, four-way switches, momentary relays, and latching relays. Emphasis is placed on methods of wiring these devices into a system following NEC procedures and interpreting blueprints and schematics. Applications include wiring switches to control lights and receptacles. Complete switching systems are formed by wiring together electrical equipment such as time-clocks, photoeyes, and relays. Single-phase transformers are used to step-up, step-down, and buck/boost voltages. DC motors are tested and connected for specific direction of rotation and speed. Corequisite: ELT 101.
