Abstract
A motor control center subunit includes a subunit housing configured to fit within a motor control center. The housing has a front panel. The motor control center subunit also includes a drive mechanism attached to the subunit housing. The drive mechanism is configured to control a plurality of line connectors to move between a retracted position and an extended position when the subunit housing is seated in the motor control center and the front panel of the subunit housing is in a closed position. A window is disposed in the front panel of the subunit housing and is positioned to provide a view of the plurality of line connectors.
