Abstract:
1. An electrical junction box that interfaces with electrical equipment in an equipment enclosure that contains harmful contaminants, comprising: a first container having walls bounding an interior that contains electrical wiring connected to the electrical equipment, the interior of the first container being in gaseous communication with the equipment enclosure to enable the contaminants from the equipment enclosure to enter the first container; an openable second container having walls bounding an interior that contains electrical junctions to be serviced; a sleeve between the containers that spaces the containers apart, the sleeve having walls bounding an interior through which the electrical wiring passes from the first container through the sleeve to the second container for connection to the electrical junctions; a seal that prevents the contaminants in the interior of the first container from reaching the interior of the second container to prevent migration of the contaminants into the second container, the seal including a cable seal sealed about the electrical wiring passing through the sleeve to the second container; and at least one of the walls of the second container being movable to open the second container to gain access to the electrical junctions to be serviced without exposure to the contaminants.
