Abstract
A watthour meter socket adapter includes a housing with electrical contacts which receive the terminals of a watthour meter and terminals which are insertable into the contacts of an electrical watthour meter socket. First and second seal connectors sealingly connect the adapter housing to the socket and a watthour meter to the adapter housing to control access to the socket, adapter and watthour meter. The interface connection includes an electrical connector mounted in an enclosure and connected to the contacts in the adapter housing to provide electrical power to an external interface. A third seal is connected and attached to the enclosure to control access to the electrical connections housed therein. In one embodiment, the enclosure is separate from and mounted on the adapter housing. In another embodiment, the enclosure is in the form of a sleeve mounted internally within the adapter housing with an open end allowing connection to an external electrical device. A body housing a voltage convertor is removably insertable into the sleeve in the socket adapter housing to convert the electrical power provided to the electrical power connector from AC to DC and to a different voltage level.
