Abstract: An improved banana jack adapter assembly is provided for use in connection with a test switch in a utility meter application. The banana jack adapter assembly improves connectability of testing equipment to a meter box test switch when a field operator desires to calibrate a meter of a utility box.

Abstract: A primary enclosure for electric power meters includes at least one shelf for supporting an instrument transformer. Slide mounts are mounted to the interior of the enclosure and to the shelf for slidably supporting the shelf for movement between a first use position in which the shelf and the transformer carried by the shelf are contained entirely within the interior of the enclosure and a second extended position wherein the shelf extends at least partially through an opening in a wall of the enclosure for servicing of the transformer The shelf can include shelf brackets attachable to the slide mounts and a transformer adapter plate to which the transformer is mounted prior to attaching the adapter plate to the adapter shelf to the shelf brackets.

Abstract: A watthour meter socket adapter carries rigid conductors extending from a connection to jaw contacts in a housing, the conductors mounting the socket adapter between the lower load mounting connections and the upper line mounting connections in a meter fitting to define an in-service metering position where the socket adapter and the watthour meter are disposed in the normal out-of-service, non-metering position in the meter fitting. The socket adapter housing is spaced from a ground terminal insulating block mounted over a ground terminal in the meter fitting. In another aspect, a plurality of current transformers are carried on a plate which mounts in an existing K-series meter fitting line and load terminal connections footprint.
