This course is recommended for journeymen. This course requires strong familiarity with the NEC and on-the-job experience of at least two years.

Recommended Prerequisite for Journeymen: Have experience with and know how to use the NEC, and have 1+ years on-the-job experience.


This course combines two of WECA’s popular 8-hour courses, “Sizing Motor Circuits” and “Wiring Motors and Air Conditioners,” into one convenient 16-hour package. ETs take these course as part of GET WIRED! 304 and Perfect Sizing, so they should not register for this individual course. In this course, electricians learn how to size single motor circuits for electrical installation.

In Sizing Motor Circuits, electricians will first learn about motors, their components, how motors function, and NEC requirements for sizing single motor circuits. Then, they practice all steps needed to accurately perform single motor circuit calculations for three different scenarios.

In Wiring Motors and Air Conditioners, you’ll learn how to size circuits used to supply power to two or more motors. You’ll also learn about air conditioning systems involving hermetic refrigerant motor-compressors and how to compare electrical circuit sizing requirements between motors in Code articles 440 and 430. Then, you’ll practice all steps needed to accurately perform motor feeder circuit and air-conditioner circuit calculations.
