Abstract:
1. A sealed electrical enclosure for use in hazardous locations for enclosing circuit breakers or other electrical components comprising: a bottom housing having a first end wall and a second end wall opposite the first end wall; a top housing positioned above the bottom housing thereby creating an internal opening adapted to receive one or more F Frame circuit breakers; a labyrinth joint or serrated joint being formed between the bottom housing and the top housing; the bottom housing adapted to receive one or more circuit breakers or other electrical components; a first metal bus extending from a point internal to the bottom housing through the first end wall to a point external to the bottom housing; a second metal bus extending from a point internal to the bottom housing through the second end wall to a point external to the bottom housing; where the first metal bus and the second metal bus are adapted to contact the first and second electrical terminals of a first circuit breaker when placed within the bottom housing; a first actuating mechanism positioned on the top housing adapted for manipulating one or more switches of circuit breakers or electrical components positioned within the bottom housing; a first vent positioned on the top housing for dissipating pressure buildup within the housing; wherein the top housing is removably secured to the bottom housing screws or bolts that are threaded into threaded inserts positioned in the bottom housing to allow for removal and replacement of circuit breakers or other electrical components within the housing; and further including a first lug retaining bracket secured to the bottom housing and extending to a position beneath the first metal bus.
