APR 127F - Advanced Electrical III

Registered Apprentice.

Course Description: Increase understanding of formulas and tables used in calculating sizing of conductors, branch circuits, breakers and junction boxes. Applications will apply to single phase and three-phase loads. A variety of motor control circuit functions including two and three wire control, peripheral devices, interlocks, and Programmable Logic Controllers (PLC’s) will be covered.

Course Learning Outcomes:

• CLO#1: Determine proper conductor size by calculating current carrying limit (ampacity). (ILO: Information Literacy)
• CLO#2: Explain branch circuits and calculate branch circuits requirements.
• CLO#3: Size branch circuits, conductors, and over-current protection for three-phase and single-phase loads.
• CLO#4: Size circuit breakers and feeder conductors for three-phase and single-phase motors.
• CLO#5: Calculate tap conductor size for three-phase and single- phase loads.
• CLO#6: Operate motor control circuits, using two and three wire control, peripheral devices, interlocks, and Programmable Logic Controllers (PLC’s).
• CLO#7: Size junction and pull boxes for conduit and wire.
