Abstract: A connector assembly includes a male connector element that is manually expandable to control tightness of fit in a and a female connector element. The male connector element is having a first and a second portion configured by longitudinally bi-furcating the male connector element and includes a chamfered portion, a radially adjusting mechanism and a screw. The chamfered portion is axially configured on male connector element and receives the radially adjusting mechanism that moves the first and second portions relative to each other. The screw axially passes through male connector element and radially moves the radially adjusting mechanism to adjust the gap between the first and second portions to adjust external dimension of male connector element.

The female connector element is having a tubular configuration that receives male connector element and is having a plurality of longitudinal slits configured thereon, walls of the female connector element are urged radially inwards towards the male connector element to maintain contact there-between by a spring element.

Abstract: A sealed electrical enclosure used in hazardous locations for enclosing circuit breakers having a bottom housing and a removable top housing with a labyrinth joint or serrated joint formed therebetween, the bottom housing adapted to receive one or more circuit breakers, a first metal bus extending from a point internal to the bottom housing through a first end wall to a point external thereto, and a second metal bus extending from a point internal to the bottom housing through a second end wall to a point external to thereto, where the first and second metal buses are adapted to contact first and second electrical terminals of a circuit breaker when placed within the bottom housing, and a first lug retaining bracket secured to the bottom housing and extending to a position beneath the first metal such that a bottom portion of a connector assembly may fit within the space between the end of the lug retaining bracket and the bottom of the first metal bus.

Abstract: A sealed electrical enclosure used in hazardous locations for enclosing circuit breakers having a bottom housing and a top housing with a labyrinth seal or joint formed therebetween, the bottom housing adapted to receive one or more circuit breakers, a first metal bus extending from a point internal to the bottom housing through a first end wall to a point external thereto, and a second metal bus extending from a point internal to the bottom housing through a second end wall to a point external to thereto, where the first and second metal buses are adapted to contact first and second electrical terminals of a circuit breaker when placed within the bottom housing, and a first vent positioned on the top housing for dissipating pressure buildup, wherein the top housing is removably secured to the bottom housing to allow for removal and replacement of a circuit breakers within the housing.
