Abstract: A multiple metering panelboard has an enclosure accommodating a plurality of watt-hour meter sections. Each section includes a molded plastic meter socket base and a molded plastic circuit breaker base mounted in interconnected relation to the enclosure in overlying relation to an array of busbars common to all meter sections of the assembly. The socket base of each section includes means for positioning at appropriate locations within the meter socket a plurality of jaws which are supported against meter insertion forces by rigid straps respectively electrically connecting the jaws to the underlying busbars and to circuit breaker line stabs mounted by the breaker base.

Abstract: A watt-hour meter socket jaw comprises a pair of upstanding contact segments which are engaged by the arms of a C-shaped spring clip. The clip includes an integrally formed tab for guiding a meter stab into electrical engagement between the contact segments. Tabs lanced from the clip arms engage in apertures in the contact segments to securely mount the spring clip to the jaw.

Abstract: In a circuit breaker load center there is provided a main lug assembly constructed for interchangeable installation with a main circuit breaker. The lug assembly comprises an insulative mounting block to which are secured a pair of conductive straps in closely spaced parallel relation. An upstanding barrier wall integral with the block provides electrical isolation between the straps, as well as between wire connector lugs affixed in electrical connection to one end portion of each strap. The block is notched to expose the other terminal end portion of each strap for electrical connection to terminal ends of the load center busbars.
