A housing includes a base with blade terminals insertable into jaw contacts in an electrical watthour meter socket. First and second watthour meter receiving shells are mounted on the housing, each having a pair of line jaw contacts connected in parallel to each other and to line blade terminals in the base. Electrical conductors extend from the load jaw contacts in one of the shells to a junction box mounted on the housing to provide a connection to an external electrical conductor. An electrical power disconnect device is mounted in one of the shells, and is connected in series by conductors between the line jaw contacts in both shells. The power disconnect device includes a movable external member having an end portion which slidably extends through the side wall of one of the shells. In one embodiment, the end portion is a separate rod which is biased into contact with the movable member. Electrical power disconnect indicia are formed on the movable external member or the rod and are visible externally of the one shell when the external member is in an extended position to indicate that the power disconnect device is in a non-power conducting state. A lock is optionally insertable through an aperture in the end portion of the external member or the rod to prevent the external member from switching the power disconnect device to a power conducting state.

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.
