A motor control center (MCC) is an assembly to control some or all electric motors in a central location. It consists of multiple enclosed sections having a common power bus and with each section containing a combination starter, which in turn consists of motor starter, fuses or circuit breaker, and power disconnect.[1] A motor control center can also include push buttons, indicator lights, variable-frequency drives, programmable logic controllers, and metering equipment. It may be combined with the electrical service entrance for the building.[2]

MCC's are typically found in large commercial or industrial buildings where there are many electric motors that need to be controlled from a central location,[1] such as a mechanical room or electrical room.
