Abstract: An interruption apparatus includes a first portion having a trip unit and a second portion having a detection system. The first and second portions are individually selectable based upon the particular application and are then movable from a detached configuration to a connected configuration. The first and second portions are selected from a plurality of first portions and second portions having different specifications. A desired first portion having a first interruption rating and a desired second portion having detection capabilities that are suited to the particular application can be assembled together to provide a field-configurable interruption apparatus.

Abstract: An automatic transfer switch includes a first switching apparatus having a first state to electrically connect at least one load to a primary power source and a second state to electrically connect the at least one load to a secondary power source; a sensor structured to sense information related to the power draw of the at least one load; and a control unit structured to determine the power draw of a selected one of the loads based on the output of the sensor, to compare the power draw of the selected load to a power capacity of the secondary power source, to allow the selected load to turn on if the power capacity of the secondary power source is at least greater than the power draw of the selected load, and to otherwise prevent the selected load from turning on.

Abstract: Apparatuses and methods for providing a capability to prevent an automatic transfer switch from automatically switching from a primary to a secondary power source are illustrated. The automatic transfer switch includes a transfer inhibitor that is configured to receive a transfer inhibit signal. In response to receiving the transfer inhibit signal, a switching logic is configured to prevent a contactor of the automatic transfer switch from automatically connecting the secondary source to a load.

Abstract: A transfer switch having a transfer control provides electric power to a load. The transfer switch includes a power switching device provided with electric power from a first power source, such as a utility power source, and a second power source, such as a generator power source. The transfer control is structured to monitor the second power source, maintain a runtime count of the second power source, locate a piece of data concerning a maintenance procedure in a storage corresponding to a current value of the runtime count, and provide an indication of a need to perform the maintenance procedure.

The transfer control is structured to monitor the second power source, maintain a runtime count of the second power source, and provide an indication of the runtime count, either at the transfer switch or at a location remote from the transfer switch and the second power source.

Abstract: An automatic transfer switch having an automatic transfer control provides electric power to a load. The automatic transfer switch includes a power switching device provided with electric power from a first power source having a first status and a second power source having a second status. The automatic transfer control is able to be operated by a mode control to set the automatic transfer control to a monitor mode in which the automatic transfer switch refrains from operating the power switching device, monitors and provides an indication of the first status and of the second status, and provides an indication of how the automatic transfer control would operate the power switching device were the automatic transfer control not set to the monitor mode.

Abstract: A transfer switch provides electric power to a load. The transfer switch includes a power switching device provided with electric power from a first power source and a second power source. During a disconnect mode, the transfer switch disconnects both the first and second power sources by causing a service disconnect interposed between the first power source and the power switching device to enter an open state and by causing the power switching device to select the first power source.
