A cover assembly controls access to the interior of an electrical enclosure. The electrical enclosure includes a housing having a panel and a plurality of walls extending from the panel to define an opening. The cover assembly includes a door-in-door assembly with first and second hinged doors and a concealed mounting mechanism. The concealed mounting mechanism secures the door-in-door assembly to the housing without requiring a separate securing mechanism. The first hinged door pivots open to access the housing without requiring the first door to be entirely removed. The second hinged door is smaller and thus provides convenient access through a cut-out portion of the larger first door. Access may be further controlled via a locking mechanism for locking the second door in a closed position within the first door.
