Motor Controls introduces students to the calculations and procedures used with conductors and protection devices. A basic understanding of motor operation, components, and circuitry is essential for these tasks. This course provides information on selecting, sizing, and installing motor controllers, as well as control circuit pilot devices and basic relay logic. Career and Technical Student Organizations are integral, co-curricular components of each career and technical education course.
