Abstract
A tamper-resistant enclosure for electrical equipment is disclosed. The enclosure includes a housing having generally upstanding and planar side walls which define a top opening. The top opening is closed by a generally horizontal and planar roof which is coextensive and congruent with the opening. Selected walls of the housing have formed at their upper edges a C-shaped structure, the open part of the C facing outwardly. The roof is formed to have a C-shaped structure around its periphery, the open part of the C facing inwardly. Facilities mount the roof to the housing so that the lower leg of the C on the roof is intermediate the legs of the C on the walls. Moreover, the upper leg of the C on the walls is intermediate the legs of the C on the roof. In this way, a labyrinth from the exterior of the enclosure to the interior is formed. Water entry through the labyrinth into the enclosure is prevented thereby, as is the insertion of wires or the like. The labyrinth, however, permits the flow of air through the enclosure around the enclosure's periphery, permitting the electrical equipment therewithin to be ventilated while remaining dry.
