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.
Many industrial processes require a large number of motors, so Motor Control Centre (MCC) panels are used to regulate them all. With the Motor control Center, the control components can be plugged in or unplugged, eliminating the need for wiring. A motor control center would consist of a bus bar and other control equipment to control the motors operation and integrate the components into a panel. Motor control Center supports several motor starting methods, including DOL and star-delta starters. A motor control center includes feeders for motors and blowers. Feeders are designed based on motor power ratings. The majority of Motor control Centers will have auto/manual options. It is possible to operate motors manually with manual provision
