Abstract: An electrical enclosure apparatus includes a protective apparatus that permits forced-air cooling of the interior of the enclosure while resisting structures that are within in the interior from being blown out of the electrical enclosure as a result of an arc event or other event. The protective apparatus includes a flow apparatus formed from one or more blocks of ceramic material having foamed therein a plurality of elongated flow channels. The flow apparatus is supported inside a duct with the use of a support apparatus. The ceramic material from which the flow apparatus is formed is configured to withstand the heat that may be experienced in an arc event and is additionally configured to be sufficiently rigid and tough to retain within the duct any structures within the enclosure from being blown out of the protective apparatus, thereby protecting personnel who may be in the area.

Abstract: A component is for an electric power system. The component includes: a user access panel; a first element for directing visible light; a second element for directing visible light, the second end of the first element facing the second end of the second element; a movable conductor structured to move between a first position and a second position; and a stationary conductor structured to engage the movable conductor. In the first position the movable conductor is disposed between the second end of the first element and the second end of the second element, thereby blocking visible light from passing from the first element to the second element. In the second position the movable conductor is not disposed between the second end of the first element and the second end of the second element, thereby permitting visible light to pass from the first element to the second element.

Abstract: An inter-pole drive bar in accordance with the disclosed and claimed concept is usable to extend among a plurality of poles of an improved switch apparatus and to cause the plurality of poles to be together moved between a CLOSED position and an OPEN position. The inter-pole drive bar is elongated and has a plurality of connection points that are connectable with the poles and further includes a number of features that avoid engagement or other interference between the inter-pole drive bar and the various structures of the switch apparatus. The inter-pole drive bar includes an elongated linkage element whose movement between the CLOSED and OPEN positions of the switch apparatus are primarily translation of the linkage element in a direction generally parallel with its longitudinal extent and translation of the linkage element in a direction generally perpendicular to its longitudinal extent.

Abstract: A secondary disconnect assembly is provided for a racking assembly of an electrical switching apparatus, such as a circuit breaker. The racking assembly movably couples the circuit breaker to a switchgear enclosure. The secondary disconnect assembly includes a mounting assembly having an elongated mounting member. The elongated mounting member has first and second opposing ends and first and second opposing sides. A sliding assembly is movably coupled to the first side between the first and second ends. A latching member is pivotably coupled to the sliding assembly. The latching member moves between an unlatched position corresponding to the circuit breaker being movable independently with respect to the sliding assembly, and a latched position corresponding to the latching member fixedly coupling the sliding assembly to the circuit breaker in order that the circuit breaker moves with the sliding assembly. The racking assembly may also include a position indicator.

Abstract: An identification system is provided for an electrical system. The electrical system includes a switchgear enclosure, a number of electrical switching apparatus, and a racking mechanism movably coupling the electrical switching apparatus to the enclosure. The identification system includes a control mechanism having a controller and a plurality of software programs. The controller includes a number of inputs from a corresponding one of the electrical switching apparatus, and a number of outputs to the racking mechanism. Each software program provides functionality to the outputs to control racking movement of a predetermined type of electrical switching apparatus. Responsive to the inputs from the electrical switching apparatus, the controller identifies the predetermined type of electrical switching apparatus, and then automatically selects a corresponding one of the software programs to control movement of the electrical switching apparatus.

Abstract: A coupling is for a racking assembly for racking an electrical apparatus into and out of an enclosure with an actuator. The electrical apparatus includes a housing. The racking assembly includes a safety interlock, which is movable between a locked position, and an unlocked position corresponding to the racking assembly being operable to rack the electrical apparatus into or out of the enclosure. The coupling includes an adapter having a first portion coupled to the racking assembly, and a second portion coupled to the actuator. A sleeve is movably disposed on the adapter. The sleeve moves the safety interlock from the locked position to the unlocked position. When the safety interlock is disposed in the unlocked position, the adapter transfers movement of the actuator to the racking assembly to move the electrical apparatus.
