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 for performing industrial automation control may include a first device that generates a first set of data formatted according to a first protocol and a second device that generates an automation command. The automation command may control the first device based on the first set of data. The second device may interpret data formatted according to a second protocol. The system may include a broker system coupled between the first device and the second device to transform data communicated between the devices, such as the first set of data, the automation command, or both. For example, the broker system may transmit a set of data generated to communicate the first set of data to the second device formatted according to the second protocol as opposed to being formatting according to the first protocol.

Described herein are improvements for a power system by operating the power system using updated performance characteristics for a protection device. In one example, a method includes operating the power system based on a first operational curve for a first protection device of the one or more protection devices. The first operational curve indicates conditions upon which the first protection device will trip. The method also provides obtaining trip information describing conditions that cause the first protection device to trip at each of one or more trip occurrences during operation of the power system. The method further provides adjusting the first operational curve to generate an adjusted first operational curve that reflects the trip information and operating the power system based on the adjusted first operational curve.
