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.
Claims24
A motor control center subunit comprising:
- a subunit housing configured to fit within a motor control center and having a front panel;
- a drive mechanism attached to the subunit housing and 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;
- and
- a window disposed within the front panel of the subunit housing and positioned to provide a view of the position of the plurality of line connectors.
A motor control center comprising:
- a frame enclosing a supply power bus, the frame having at least one compartment;
- a subunit housing constructed to seat in the at least one compartment of the frame;
- at least one conductive contact disposed within the subunit housing;
- an actuating mechanism attached to the subunit housing and configured to move the at least one conductive contact between an engaged position and a disengaged position;
- and
- a view port disposed within the subunit housing and configured to permit a visual confirmation of the disengaged position.
A method of manufacturing a motor control center subunit comprising:
- constructing a motor control subunit to seat in a motor control center;
- constructing a front panel for the motor control subunit;
- disposing a viewing window within the front panel;
- locating at least one conductive connector within the motor control center subunit;
- and
- providing for advancement of the at least one conductive connector when the front panel is in a closed and locked position to supply power to the motor control subunit.
