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.
