Abstract
A mounting base apparatus for an electrical power measuring device such as a watt-hour meter, that is especially adapted for use in residential applications and providing a lightning arrester for the mounted meter. The apparatus includes one piece molded plastic a one piece molded plastic base structure including a circular base having a forwardly extending tubular side wall for forming a partially enclosed cavity. The tubular side wall terminates in an external flange forming a substantially planar circular surface having a concentric opening for receiving the watt-hour meter. Mounted on the base within a partially enclosed cavity formed by the side wall and base are a plurality of electrical terminals. The terminals receive a corresponding plurality of blade terminals on the watt meter to electrically connect the watt-hour meter. Mounted within the cavity is an electrical conductor or shunt gapped sufficiently from the terminals to prevent electrical arcing through the conduit at normal voltages while providing grounding safety protection against undesired power surges caused by lightning and the like.
