Abstract

A plane change connector assembly is provided which connects electrical busbars which are in different planes. The assembly includes a connector which has at least one coupling flange cantilevered from one side of a planar joining member. A second coupling flange is cantilevered from the other side of the planar joining member in a different plane from the first coupling flange and preferably, in a plane at a right angle to the plane of the first coupling flange. The connector can be used as part of an assembly for connecting multiphase systems having multiple co-planar busbars for each phase. In this preferred form, the connector is provided with multiple coupling flanges, and a connector is associated with each phase of the system. The co-planar busbars for each phase are connected with plates which in turn engage the first coupling flanges of the connector. Similar plates engage the second coupling flanges which are in a different plane from the first coupling flanges and the two systems which are in different planes are thereby connected.
