Complete three self-paced courses in this order:

Sizing Motor Circuits
    • In this course, electricians learn how size single motor circuits for electrical installation. First, electricians 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 this course, you will learn how to coordinate (bring together) information in specific NEC articles, so you can properly select and install the correct electrical circuit components and conductors needed for different load and circuit configurations.

Wiring Motors and Air Conditioners
    • 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.
