ABSTRACT:
A meter socket adapter includes an insulating housing that is connected to a power circuit on one side by bus bars and connected to a watt-hour meter on the other side by jaw contacts. The housing includes insulating compartments for current transformers through which the bus bars extend. Current transformers extend around the bus bars and are housed in individual compartments in the current transformer housing. Transformed current is directed to the jaw contacts for metering with the watt-hour meter. The bus bars include an insulating layer there on, reducing the need for insulation around the secondary of the current transformers. The current transformers are then significantly smaller and fit within a K-Base meter socket. The adapter housings define a cavity with separate dielectric plates between the bus bars and the jaw contacts. The adapter conveniently allows for self-contained meters to be used in high current installations.
