  • Power distribution system
    Patent number: 11450998
    Abstract: 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.
