What is a motor control center (MCC)?
The apparatus designed for this function is the motor control center (MCC). Motor control centers are simply physical groupings of combination starters in one assembly. A combination starter is a single enclosure containing the motor starter, fuses or circuit breaker, and a device for disconnecting power.
What should I look for when installing a motor control center?
Check for the location of installation is free of any water or construction debris. Ensure that the MCC are properly tagged & identified location wise and service wise as specified. Ensure that the wiring termination to the Motor Control Center are complete & are tight & secure.
What is the range of a motor control center?
Voltage ranges. Motor control centers are usually used for low voltage three-phase alternating current motors from 208 V to 600 V. Medium-voltage motor control centers are made for large motors running at 2300 V to around 15000 V, using vacuum contactors for switching and with separate compartments for power switching and control.
