Abstract
Abstract An electric power meter and distribution box suitable for use in mobile home parks and similar outdoor applications in which underground wiring is brought up through a vertical hollow stand pipe to which is affixed a base member by means of first and second pairs of set screws. The base member is adapted to support an enclosure in which is located one or more duplex receptacles, a set of circuit breakers, an electrical watt-hour meter, as well as any other similar type of power receptacles. The first pair of set screws is located external to the enclosure whereas the second pair of set screws is located within the enclosure. A hinged cover member, which may be locked, is provided to prevent unauthorized access or tampering with the electrical components.
