  • Patent number: 5239441
    Abstract: A fault locating system for locating a fault in an underground power distribution system includes a method and an apparatus. The underground power distribution system receives and distributes power from a bulk power source to power consumers through a fused switchgear unit and a first vault. The first vault distributes power from the fused switchgear unit among plural outgoing underground power lines, with each line supplying power to at least one power consumer. A current limiting apparatus for locating faults in the above system includes an enclosure of an insulative material defining a fuse receiving chamber. First and second bushings extend through the enclosure to the fuse receiving chamber. The apparatus has a current limiting fuse received by the respective first and second bushings within the fuse receiving chamber.

  • Patent number: 5230552
    Abstract: A module is provided for communicating utilities to a worksurface or the like from a remote source. The module includes a housing which is pivotally mounted within an aperture in the worksurface. The housing has a hollow interior for receiving one of a plurality of utility connector modules, such as an electrical or communication receptacle. The housing is pivotable between an open position wherein the receptacle is exposed and accessible, and a closed position wherein the receptacle is substantially hidden or retracted. In the preferred embodiment, the housing naturally moves to a closed position so that the receptacles are protected by an upper surface on the housing that is contoured to direct any spilled fluids away from the receptacle when the housing is in the closed position. Also in the preferred embodiment, the receptacles are oriented so that any spilled fluids flow away from the receptacles.
