Abstract: A racking assembly for an electrical apparatus is provided. The racking assembly includes a movable carriage assembly and a drive assembly. The movable carriage assembly is sized to fit within a housing assembly and is structured to be moved between a first position and a second position. The carriage assembly is further structured to support at least one electrical component. The drive assembly includes a motor assembly and a positioning assembly. The motor assembly is structured to impart movement to said positioning assembly. The motor assembly is coupled to said positioning assembly. The positioning assembly is structured to impart movement to said carriage assembly and to move said carriage assembly from said first position to said second position. The positioning assembly is coupled to said carriage assembly. In this configuration, the racking assembly is structured to move the carriage assembly, and therefore the electrical apparatus, between the first and second positions.

Abstract: A submersible electrical enclosure is for a switchgear assembly. The switchgear assembly includes a number of electrical switching apparatus. The submersible electrical enclosure includes: a plurality of sides defining an interior, the interior receiving each of the electrical switching apparatus, each side including: a conductive polymeric layer facing away from the interior, and an insulative polymeric layer molded to the conductive polymeric layer. The insulative polymeric layer faces the interior and substantially overlays the conductive polymeric layer.

Abstract: An improved vent apparatus that is usable with an electrical enclosure includes a vent flap that is movable between a closed position overlying an opening formed in a wall of the electrical enclosure and an open position wherein at least a portion of the vent flap is spaced from the wall. The vent flap may be held in place in the closed position via gravity or through the use of a retainer such as a spring or a frangible structure. The vent flap is a part of a flap apparatus that is formed as a unitary single piece element that may be stamped from sheet metal, for example, and the flap apparatus includes a number of hinge elements that are rollably disposed on an edge of the wall adjacent the opening.

Abstract: An electrical disconnect includes a housing having a recess defined therein extending from an opening toward a base. The disconnect also includes a vacuum envelope defined within the housing near the base; a fixed contact assembly including a fixed contact structured to be in electrical communication with a voltage source disposed partially within the vacuum envelope; and a movable contact assembly including a movable contact having a first end disposed within the vacuum envelope and a second end disposed in the recess near the base and movable between a closed position in electrical contact with the fixed contact and an open position spaced apart from the fixed contact a separation distance. The housing includes a dynamic shield electrically connected to the movable contact, the dynamic shield being disposed about the recess within the housing and extending from the base toward the opening thereof.

Abstract: A mechanical interlock assembly for a network transformer primary disconnect assembly is provided. The mechanical interlock assembly includes a blocking member assembly with a body. The a blocking member assembly body includes an obstruction portion and a lacunar portion. The blocking member assembly is movably disposed adjacent to a movable operation contact carriage and a ground contact carriage. The blocking member assembly body is movable between a first position, wherein the blocking member assembly body obstruction portion is disposed in the path of the ground contact carriage, a neutral position, wherein the blocking member assembly body obstruction portion is disposed in the path of the ground contact carriage and the operation contact carriage, and a second position, wherein the blocking member assembly body obstruction portion is disposed in the path of the operation contact carriage.

Abstract: A housing assembly for a network transformer primary disconnect assembly is provided. The housing assembly includes a visible break assembly and a number of sidewalls defining an enclosed space. The visible break assembly includes a number of viewing windows in at least one sidewall. The viewing windows are aligned with one of a contact assembly interface or a movable contact assembly distal end in the open, first position.

Abstract: An adjustable wireway assembly for use in an electrical enclosure includes a panel structured to form a portion of the electrical enclosure, the panel having a first aperture defined therein. The assembly further includes a plate member selectively coupled to the panel about a portion of the first aperture in at least one of a first position and a second position in a manner that blocks at least a portion of the first aperture and thereby defines a second aperture formed from a portion of the first aperture. When coupled in the first position, the second aperture is of a first area and when coupled in the second position, the second aperture is of a second area different than the first area.

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: A coupling is provided 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.
