Abstract: An electrical enclosure, such as a Motor Control Centers (MCC), can include a ventilation system providing airflow while protecting from both ingress of solid objects as small as 1.0 millimeter and egress of gasses from an arc flash by providing a protective mesh with holes having a dimension of less than 1 millimeter, a bracket coupled to the mesh for providing a rigid support, and a flap configured to seal against the bracket and block the mesh in response to a pressure wave produced by an arc flash. The flap, normally open for airflow, can close in response to the pressure wave, by bending at a perforation line to move the flap toward the mesh. The electrical enclosure can also include a normally closed exhaust system. The exhaust system can be configured to open in response to the pressure wave to allow the gasses to escape.

Abstract: For latching an equipment unit door of an equipment unit in a control center, an apparatus includes a latch pin, the unit socket, and a structure socket. The latch pin includes a latch shaft with a latch interface disposed on a pin proximal end and a latch wing disposed on a pin distal end. The latch pin rotates to one of an open position, a unit latch position, and a structure latch position. The unit socket passes the latch wing in the open position and obstructs the latch wing from moving in a proximal direction in the unit latch position. The structure socket passes the latch wing in the unit latch position and obstructs the latch wing from moving in the proximal direction in the structure latch position.

Abstract: A terminal assembly may be provided which utilizes an electrically insulating cover to electrically isolate upper portions of screw terminals. The electrically insulating cover could be made from plastic, rubber or some other electrical insulator, and could be mounted on a frame configured to engage with a frame supporting the screw terminals. While lower portions of the screw terminals may continue to electrically connect with electrical connectors for receiving load stab conductors (from a unit), upper portions of the screw terminals may be electrically isolated to protect from short-circuit, and/or shock, such as while a door or access panel of a wire-way is removed. The electrically insulating covers may also include cable glands for circumferentially surrounding wires leading to the screw terminals. A retainer clip may also be used to securely hold the electrically insulating covers to the frame supporting the screw terminals.

Abstract: The detrimental effects of environmental hazards on units having withdrawable stabs or contacts may be overcome by using fixed feed units in compartments in a manner akin to withdrawable units. In particular, multiple fixed feed units may be provided in a single section or column by implementing vertical bus bars providing multiple connection points particular to fixed feed units. As a result, fixed feed units may be mounted to the vertical bus bars, as opposed to horizontal main bus bars or requiring complex wiring, thereby allowing multiple fixed feed units to be efficiently provided to maximize space. An electrically insulating bus support, which may be supplemented with bracing, may provide improved short-circuit protection. Electrically insulating covers over fixed feed unit connections may also provide electrical isolation in the system in accordance with industry standards. Moreover, in one aspect, fixed feed units and withdrawable units may be intermixed.

Abstract: Embodiments of this present disclosure may include a handle disposed on an outer surface of a housing of electrical circuitry. The handle may provide access to at least a portion of the electrical circuitry. The handle may include a status indicator that emits light in response to a control signal from control circuitry. The status indicator may be disposed around the handle. The control circuitry may detect a state of the electrical protection circuitry. The control circuitry may also transmit the control signal to the status indicator based on the state. The control signal may control one or more properties of the light emitted by the status indicator, and thus indicate to an operator the state of the electrical circuitry.

Abstract: A stab for use in a plug-in assembly includes a stab piece and a lug. The stab piece includes one or more contact arms configured to engage a bus bar, and a base portion coupled to the one or more contact arms. The base portion is configured to be coupled to a stab shaft for rotating the stab about a rotational axis to transition the stab from a retracted position to an extended position. The lug is coupled to the stab piece and configured to receive wire for transmitting power from the bus bar to an electrical component. The lug is configured to be deformed around the wire to hold the wire when a crimping force is applied to the lug. The lug is configured to hold the wire at a position approximately centered on a rotational axis of the stab shaft when the lug is deformed by the crimping force.
