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.
