A connecting arrangement for a three-level converter arrangement includes a first to third connection rail which are each in the form of a shaped metal body. The respective connection rail has a line section and a connection section which has a connection means. The respective connecting rail has a line section and a connecting section which, for its part, has an associated respective connecting means. The respective connection means forms, with the connecting means, a force-fitting, electrically conductive connection. The connection rails are connected to the connecting rails with the correct polarity. The respective line sections of the connection rails and the connecting rails are situated one above the other in a stack, wherein the first connecting section, in projection in the normal direction of the first connection section, covers the first connection section; wherein the second connecting section, in projection in the normal direction of the second connection section, covers the first connection section and the second connection section, and wherein the third connecting section, in projection in the normal direction of the third connection section, covers the second connection section and the third connection section.

A bus bar assembly includes bus bars and a bus bar holder that is made of an insulating material and holds the bus bars in a non-contact state. The bus bars include base portions that overlap with other bus bars in the axial direction, and connecting portions extending from the base portions along the radial direction. At least two of the bus bars include stepped portions extending toward the other bus bars between proximal ends of the connecting portions and connection ends connected to windings. The bus bar holder molds the base portions and the stepped portions in a state where the connection ends are exposed.

An electrical system for use in a raceway includes a power cable and a junction block. The junction block includes junction block halves configured to form opposing halves of the junction block, a plurality of bus bars arranged within a bus bar cavity, and a hinged connector arranged on a face of a first of the junction block halves. The junction block halves are coupled to define a bus bar cavity within the junction block. Each of the bus bars are electrically coupled to a conductor of the power cable. The hinged connector is arranged opposite a second junction block half such that a portion of the hinged connector is rotatable about an axis that is parallel to a face of the first junction block half. The power cable is coupled to the junction block via the hinged connector.

A power distribution system includes a track having a first end, a second end opposite the first end, and a longitudinal axis extending through the first and second ends. The track defines a channel extending along the longitudinal axis. A plurality of power cables is positioned within the channel. The power distribution system further includes an electrical hub having a body coupled to the second end of the track. A plurality of wafers is supported by the body and stacked on top of each other to define a set of terminals. The set of terminals is electrically connected to the plurality of power cables. A power receptacle is supported by the body and electrically connected to the plurality of wafers.
