Motor Control Centers (MCCs)

A Motor Control Center (MCC) is the assembly that controls some or all of the motors from a central location. It consists of multiple enclosed sections with a common power bus, each containing a combination starter which in turn consists of a motor starter, a fuse or circuit breaker, and a power disconnect. Motor control centers can also include buttons, indicator lights, variable frequency drives, programmable logic controllers, and metering devices. They are often found in large commercial or industrial buildings where there are many electric motors that need to be controlled from a central location such as a mechanical or electrical room.
