A motor control center includes an enclosure comprising an isolation switch, a main contactor device, and a ground switch device. The isolation switch is selectively manually operable between a connected state and a disconnected state. In the connected state the isolation switch is adapted to conduct electrical power from an associated power source to the main contactor device and wherein the isolation switch in the disconnected state interrupts conduction of electrical power from the associated power source to the main contactor device. The main contactor device is selectively operable between a conductive state and a non-conductive state, wherein the main contactor device is adapted to electrically connect the isolation switch to the ground switch device and to an associated electrical load when the main contactor device is in its conductive state and wherein the main contactor device disconnects said isolation switch from the ground switch device and the associated electrical load when the main contactor device is in its non-conductive state. The ground switch device is manually operable from an open, ungrounded state in which the main contactor device is electrically disconnected from a ground path to a closed, grounded state in which the main contactor device is electrically connected to the ground path. The motor control center further includes an interlock device operably connected between the isolation switch and the ground switch device, wherein the interlock device prevents movement of the isolation switch from the disconnected state to the connected state when the ground switch device is in the grounded state.

A system includes a multidrop cable and a connector. The connector is configured to couple to one or more MCC withdrawable units installed in one or more respective buckets of an MCC, wherein the connector is configured to couple the one or more MCC withdrawable units to, and decouple the one or more MCC withdrawable units from, the multidrop cable without disrupting a network or a subnet of the MCC.

A motor control center (MCC) for an industrial automation system, includes an enclosure housing comprising a plurality of sections, including a first section having one or more buckets, including a first bucket, a first bus bar, a second bus bar, and a third bus bar extending horizontally across the first section along a back plane of the enclosure housing, and a first electrical component, configured to perform one or more functions of the MCC, disposed within the first bucket of the first section. The first electrical component is directly electrically coupled to the first set of bus bars such that the first electrical component draws a first phase of power from the first bus bar, a second phase of power from the second bus bar, and a third phase of power from the third bus bar.

Electrical power distribution devices with a bypass unit that electrically engages one of two alternate units for powering a load while electrically isolating the other using a six pole power transfer switch and mechanical and electrical interlocks to allow a technician to access one of the alternate units when de-energized and in position while the other of the alternate units is energized and powering the load.

A power distribution system is releasably secured to a power distribution panel, and includes a circuit breaker to detect a fault condition and to automatically move a circuit breaker switch from the ON position to the OFF position. The power distribution system further includes a backplane connector to provide connection to the power distribution panel and an interconnect mechanism to connect the circuit breaker to the backplane connector when the circuit breaker is moved from a disengaged position to an engaged position with respect to the backplane connector. The power distribution system further includes a guard coupled to the interconnect mechanism and configured to cover portions of the enclosure of the circuit breaker. The guard further prevents the circuit breaker switch from moving from the OFF position to the ON position until the interconnect mechanism connects to the circuit breaker to the backplane connector.
