Abstract
An electrical enclosure including a box and a cover is molded largely of plastic, but is intended for use with metallic conduit. One or more metallic inserts is molded within the box, and also another insert is molded within the cover, to provide ground continuity to all fully or partially contained wiring or control devices as well as to provide ground continuity to conduit leading into the box. The electrical enclosure optionally is explosion proof, requires a minimum of machining, provides means for the harmless run-off of all static electrical charges, and exposes a minimum of metallic surface area to the surrounding atmosphere which may contain metal degrading contaminants.
