Abstract: In one aspect, a set of male and female bus bars is provided. The male bus bar includes first and second conductors and an insulation layer therebetween. The male bus bar has a male connecting portion with one or more fingers. The female bus bar third and fourth conductors and an insulation layer therebetween. The female bus bar has a female connecting portion with one or more receptacles, each having contact surfaces that are free of insulation and that are positioned to contact contact surfaces on an associated finger which are free of insulation so as to connect the first conductor and the third conductor and to connect the second conductor and the fourth conductor. Each finger has a width. A gap exists between the contact surfaces of an associated receptacle. The width and gap are sized to provide a press fit between the fingers and the receptacles.

Abstract: A bus bar connection interface including a first conductor having a first end, a second end, and a cavity, an insert of electrically conductive material having a top end, a bottom end, and a waist portion therebetween and the insert being configured to fit into the cavity of the first conductor such that the insert and the first conductor are in electrical communication. A second conductor having a first end and a second end configured to receive the insert such that the insert and the second conductor are in electrical communication when engaged. The waist of the insert being in contact with the second conductor and at least one of the top end and the bottom end of the insert being in contact with the first conductor to maintain electrical conductivity between the first conductor and the second conductor.
