Plug-in circuit breaker assembly including insulative retainers

A circuit breaker assembly comprising:

• a housing;
• an electrical bus structure within said housing;
• a plurality of plug-in members coupled to said electrical bus structure;
• a number of insulative retainers coupled to said electrical bus structure, a corresponding one of said number of insulative retainers being operatively associated with a corresponding number of said plurality of plug-in members, wherein each of the number of insulative retainers is an electrical insulator that includes a base adjacent the electrical bus structure and at least one elongated portion extending from the base, said base defining at least one first aperture therein, each of said at least one elongated portion defining a second aperture therein and a conduit extending therethrough from a respective one of the at least one first aperture to the second aperture, wherein the conduit has a generally cylindrical shape and a surface of the conduit includes a plurality of internal ridges, and wherein for each of the number of insulative retainers in a plane view of the base, the base has a greater area than a combined area of said at least one elongated portion extending from the base;
• a number of circuit breakers, each of said number of circuit breakers comprising a manual operator disposed from a first surface and a plurality of female sockets disposed from a second surface opposite the first surface, each of the plurality of female sockets electrically engaging a corresponding one of said plurality of plug-in members, each of the female sockets including a portion that extends in a direction opposite each of the manual operator so as to receive the corresponding one of the plurality of plug-in members therewithin while also engaging a respective insulative retainer of the number of insulative retainers;
• and
• a cover member removably coupled to said housing, said cover member comprising a third surface and a number of apertures disposed through the third surface;
• wherein the first surface of each of said number of circuit breakers engages the third surface of said cover member,
• wherein said manual operator passes through a corresponding one of said number of apertures, and
• wherein each of said female sockets has a cylindrical shape within the generally cylindrical shape of the conduit and is engaged by said internal ridges of the conduit so as to retain a corresponding circuit breaker of the number of circuit breakers with the manual operator generally facing downward when the cover member is removed from the housing.
