SQUARE D MODEL 6 15 AMP BREAKER SIZE 1 MCC MCCB BUCKET *BOX

An MCC houses multiple motor control and feeder units in a modular arrangement. A feeder bucket is a section (or “bucket”) in the MCC that feeds power (rather than directly controlling a motor). It contains the disconnecting device / circuit breaker, bus connections, etc. This particular feeder bucket is from Square D’s Model 5 line. The “6-inch” refers to the vertical module height (i.e. the “bucket height” or “unit size”) used in the MCC line.
