Motor Control Center

A Motor Control Center (MCC) is an assembly that controls several or all-electric motors centrally. There are multiple enclosed sections and a common power bus. Each section has a combination starter, which consists of a motor starter, fuses or circuit breakers, and a power disconnect. It is also possible to equip a motor control center with push buttons, indicator lights, variable-frequency drives, programmable logic controllers, and metering equipment. In some buildings, it may be combined with the electrical service entrance.

Typically, Motor Control Centers can be found in large industrial or commercial buildings containing a lot of electrical motors that must be controlled centrally, such as an electrical room or mechanical room.
