In our homes, the small-sized electrical motors are usually directly started by providing voltages. However, in industries, the power is provided to motors from customized load centers that are used to serve small to midsize motors. Technically these load centers are known as Motors control centers. In this post you’ll learn what are motor control centers and why do we need them.

What is a Motor Control Center

A motor control center is an assembly of electric switching and control components that is intended for switching and control of electric motors.

The figure below displays a motor control center intended for control of 480 V motors in an industrial plant.
