Title: Integrated bushing component

Abstract: An integrated bushing component for use in conjunction with pad mounted high voltage three-phase switch gear located with an electrical cabinet. The integrated bushing component providing an electrically insulated conductive path through a dead front barrier separating a first switch gear confinement area, wherein a first electrical circuit is connected to the switch gear mounted therein, and an second electrical connection confinement area, wherein connection to a second electrical circuit is provided by an end of the integrated bushing component. The switch gear includes a switch arm selectively positionable between an open non-conducting position and a closed conducting position. The switch arm provides a primary conductive path connecting a first electrical circuit with a terminal when the switch arm is placed in the closed conducting position. The integrated bushing includes, in a unitary component, a conductive inner core and a pump housing which receives an electrical arc extinguishing pump therein. The arc extinguishing pump defines a movable contact to provide a secondary conductive path between the terminal and a probe connector conductively attached to the switch arm so as to contain and extinguish an arc created upon movement of the switch arm form the closed position to the open position.
