What are the benefits of motor control centers?
A. They protect against short circuits and other electrical faults.
B. They provide electrical isolation for motors for personnel protection during maintenance.
C. They provide interlocks that prevent the motor from running in configurations that would damage it.

A. Incorrect. Motor control centers (MCCs) provide protection against short circuits and other electrical faults. They protect the motor against overloading that could result in overcurrent, which could damage the motor. MCCs can also protect against motor overspeed and can provide interlocks that prevent the motor from running in configurations that would damage it or other process equipment. And finally, MCCs are used to electrically isolate motors for personnel protection during maintenance.
