Claim:
1. An electrical enclosure assembly comprising: a housing comprising a rectangular bottom wall, a plurality of side walls extending from the bottom wall, and an interior opening; a cover; a door; a door frame attached to the housing; and a plurality of detents, wherein the door is hinged to the door frame, said interior opening can be closed when the door is in a closed position and open when the door is in an open position, said cover is hinged to one of the sidewalls of the housing and covers the door frame and the door when the cover is in a closed position, and said detents are mounted on an inner surface of the bottom wall, wherein the door frame comprises four side edges, a plurality of flexible locking tongues mounted to two opposing of the four side edges, respectively, the door frame can be locked to one of the plurality of side walls of the housing when the locking tongues are received in the detents and the door frame is in the locked position, and the door frame can be released from the housing when the locking tongues have been opened and released from the detents, wherein each of the locking tongues is arranged to receive a first manual force and to strain and flex when the door frame is being installed to the housing by moving the locking tongue towards a bottom of the housing, and once the door frame is installed on the housing, the locking tongues are at the detents and unstrained or a second manual force is directed on the locking tongues, which is smaller than the first manual force, and, correspondingly, the straining and flexing of the locking tongues are smaller than the flexing and straining thereof when the door frame is being moved towards the bottom of the housing, and wherein the door frame covers the interior opening so that access to the locking tongues, in order to open the locking position of the locking tongues, requires the door to be opened, whereby as the door is opened, a first surface of each of the locking tongues may be accessed in order to apply a manual external force on the first surface so that the locking tongues flex and the locking tongues are released from the detents in the housing, whereby the door frame may be lifted off the housing.
