ABSTRACT:
This invention relates to a safety cover assembly for a meter socket having a plurality of electrically-energizable contacts adapted to receive the rearwardly-projecting contact blades or terminals of various types of electrical meters including those used for measuring both commerical and residential power consumption. The socket normally has a substantial number of electrical contact elements in suitable spaced-apart alignment to receive the projecting contact terminals of various types of meters to energize one or more electrical circuits within the meter to determine both the accuracy and efficiency of the meter. The cover assembly is preferably formed of transparent plastic insulating material having high dielectric constant including an outer apertured cover plate to provide an essentially dead front to the meter socket when energized, both when a meter is mounted in and demounted from the meter socket. The components of the meter cover assembly are preferably comprised of durable transparent insulating material for visual inspection of the wiring, internal electrical contacts and connections, the socket being designed for both laboratory and field applications.
