1. An auxiliary equipment enclosure unit mountable both at a ring-type watthour meter socket having a sealing ring and at a ringless-type watthour meter socket having an enclosure cover, said enclosure unit comprising:
- a hollow body defining a housing portion adapted to receive separate equipment devices therein; and
an adaptive socket attachment assembly including a mounting extension extending axially from the rear end of said housing portion and having an outer periphery circumscribing an area less than the vertical cross sectional area of said housing portion with said mounting extension including a circumferential groove, said adaptive socket attachment assembly further including a resiliently expandable and removable retainer means resiliently positionable in said circumferential groove so as to be axially confined therein,said enclosure unit, when mounted to a ring-type watthour meter socket, being mounted in an abutting relationship to said ring-type watthour meter socket, with said retainer means being maintained in a predetermined radially overlapping relationship with the sealing ring of said ring-type watthour meter socket such that said sealing ring retains said enclosure unit at said ring-type meter socket,said enclosure unit, when mounted at a ringless-type meter socket having both said mounting extension and said retainer member inserted in said ringless-type watthour meter socket such that the enclosure cover thereof retains said enclosure unit at said ringless-type meter socket.

21. An auxiliary equipment enclosure unit for interposed mounting between a watthour meter socket and a detachable watthour meter having rear blade terminals, said enclosure unit being mountable with both ring-type sockets having a sealing ring and ringless-type sockets having an enclosure cover, said enclosure unit comprising:
-
a body including a central housing portion having a front end for attachment to the detachable watthour meter and a rear end, the interior of said housing portion adapted to receive and enclose auxiliary equipment devices therein; an adaptive socket attachment assembly including a mounting extension extending from a vertical back wall surface of said housing portion, said mounting extension including an annular groove around the circumference of said mounting extension, said adaptive socket attachment assembly further including a retainer means having a split ring configuration and receivable by said annular groove of said mounting extension in a resilient snap on fashion and extending radially outward therefrom to define a rim surface having a predetermined diameter, upon said enclosure unit being mounted at a ring-type meter socket said mounting extension is in an abutting relationship with said ring-type meter socket and said retainer means is in a predetermined radially overlapping relationship with the sealing ring of said ring-type meter socket such that said ring retains said enclosure unit at said ring-type meter socket, upon said enclosure unit being mounted at a ringless-type meter socket both said mounting extension and said retainer means are inserted therein such that said enclosure cover retains said enclosure unit at said ringless-type meter socket; a plurality of blade terminal extensions including straight conductive bar members with bifurcated forward ends for receiving each of the meter blade terminals within flat overlapping contact areas along both sides thereof; and a plurality of threaded clamping members each fixedly attaching the bifurcated forward ends of the blade extensions to the meter blade terminals received therein. - View Dependent Claims (22, 23, 24, 25, 26, 27)
