An electrical power distribution system includes at least one circuit protection device and a housing defining an interior space to receive the at least one circuit protection device. The housing includes a door positionable between an opened position in which the door allows access to the interior space and a closed position in which the door inhibits access to the interior space. The housing also includes a hinge pivotably coupling the door to the case and a pressure release mechanism coupled to the door and the hinge. The pressure release mechanism includes a tongue positionable between a first position and a second position and a biasing member arranged to bias the door towards the case when the door is in the closed position.
