  • Publication number: 20230127324
    Abstract: A utility meter includes an electrical conductor portion, a service switch, and a heat sink. The electrical conductor portion provides electrical communication between a supply line terminal and a load line terminal, and the supply line terminal electrical communication an electrical source. The service switch is selectively operable to interrupt electrical communication between the supply line terminal and the load line terminal. The heat sink is in thermal communication with the electrical conductor portion to dissipate heat generated by a current passing through the electrical conductor portion between the supply line terminal and the load line terminal.

  • Publication number: 20050270016
    Abstract: An electronic residential electricity meter includes a base assembly having a main body and the base assembly includes a current transformer mounted to the main body. A first conductor is mounted through a window of the current transformer. The first conductor and the current transformer are configured to measure a load current and the current transformer is configured and dimensioned to operate when the load current includes a direct current. The meter also includes an electronic module that has only one printed circuit board and a microcomputer for executing meter data operations. The current transformer and the first conductor are in electrical communication with the electronic module. A method of assembling an electronic residential electricity meter includes mounting a first conductor and a second conductor through a window of a current transformer.
