  • Patent number: 5033973
    Abstract: A service disconnect adapter mounted between a plug-in meter socket and a watthour meter. The service disconnect adapter has blades mounted on a base which engage terminals in the socket. Watthour blade receiving fingers are formed in the service disconnect adapter to receive and frictionally engage watthour meter blades. The service disconnect adapter electrically isolates the socket load terminals from the watthour meter blades to disconnect the watthour meter from the load side terminals of the socket. The blades are angularly offset from the watthour meter blade receiving fingers in the adapter to mount the watthour meter at an angle from its normal mounting position.

  • Patent number: 4977482
    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.

  • Patent number: 4622753
    Abstract: A repair kit for an electric meter socket, which includes a set of jaw contacts mounted on a support plate, with means for mounting said plate in a desired spaced relation to the back of the meter box so that the blade contacts of the meter will be inserted into the jaw contacts for a suitable depth when assembled, and a template for temporarily mounting into the meter aperture in the meter box cover, said template having a series of guide holes for receiving a punch for marking the position for plate mounting holes in the back of the meter box, and means for orienting said template so that said holes will be in a position such as to allow the meter to be in a desired orientation after assembly.
