Basics of Motor Control Centers (MCCs)

At its core, a Motor Control Center consists of a series of buckets housed within a larger structure. In industrial and manufacturing environments using electric motors, a system is necessary to control these motors, and that's where the motor control center plays a crucial role.

How They Operate

Feeder buckets are responsible for powering and controlling the electric motors, typically with one bucket per motor. Given that industrial processes often involve numerous electric motors, multiple buckets are required to manage the entire system. The structure serves as the vertical housing, conveniently holding and controlling all feeder buckets in a central location.

The buckets within the structure come in various sizes and configurations, such as fused or circuit breakers. Additionally, these buckets are fully removable, providing flexibility for the electric system to adapt to changes in industrial processes. For instance, adding or removing motors is simplified by adding or removing buckets from the structure or swapping them out for the appropriate components.
