Students will construct typical circuits based on ladder diagrams and wiring diagrams for single-phase and 3-phase electric motors. Control stations will include stop/start pushbuttons, selector switches, photo-eyes, limit switches, and toggle switches. Diagrams of single stations, dual stations, jogging, and reversing push button stations will be included. Interlocking of motor starters will include mechanical, electrical, and push button interlocks. Timers and relays will be used in conjunction with motor control circuits’ in general industrial plant applications. Devices such as a pilot light will be added to each circuit as well as proper fuse control, and safety disconnects. PREREQUISITE: IET 113 Industrial Electricity; IET 114 Industrial Wiring
