    摘要: An electric circuit jumper cable assembly having a plurality of leads electrically connected serially at first ends of the leads to form an electrical junction within a bus within a housing; a plurality of terminals individually connected at second ends of the leads, each terminal having: a base, an electrically conductive tip in the base electrically connected to one of the leads; and a cover element relative to the base that selectively shields at least a portion of the electrically conductive tip. The electric circuit jumper cable assembly is useful for convenient testing of electrical circuits.

    摘要: An electrical power infeed module for modular electrical power systems selectively provides power to one or more electrical outlets in the system from a single power source, regardless of the number of power sources are engaged by power infeed modules in the system. The power infeed module includes a power infeed cable, a power output cable, and an electrical circuit disposed between the power infeed cable and the power output cable, the electrical circuit being operable to selectively connect the power output cable to the power infeed cable if the power infeed cable is connected to a first power source and the power output cable is not already electrically energized by a second power source. The circuit includes an electrical switch, a sensor for detecting whether the power output cable is electrically energized, and a controller for operating the switch in response to a signal from the sensor.

    摘要: An improved bus bar apparatus is usable in high temperature electrical terminations and is configured to provide sufficient heat dissipation such that when connected at one end with a 90° C. wire, the bus bar apparatus is at most only at 75° C. at another end thereof, which end can be connected with a lower temperature electrical component such as a circuit interrupter. The bus bars apparatus may include bus bars that extend directly between the high temperature wires and the low temperature electrical component, or the bus bar apparatus may additionally include wires that are electrically interposed between the low temperature region of the bus bars and the electrical component. Additional cooling could be provided by employing oversized wires. The bus bars may additionally include fins, fans, or supplementary heat sinks to enhance thermal convection of the bus bar. The bus bar apparatus additionally can be provided with its own enclosure to be usable in a retrofit situation.

    摘要: A junction box assembly configured to shield the eyelet terminal includes a power distribution box and a bottom housing. A bottom housing is configured to mate with an undersurface of the power distribution box. The eyelet terminal is disposed within the bottom housing. A first connection housing is disposed in the bottom housing. The first connection housing is configured to house a first bus bar having a female connector. The first bus bar is electrically connected to the eyelet terminal. A second connection housing is disposed on an undersurface of the power distribution box. A second bus bar is mounted within an inner space of the power distribution box and a connecting portion of the second bus bar is disposed within the second connection housing. The first connection housing engages the second connection housing within the bottom housing so as provide a shielded.

    摘要: A busway system is provided. The busway system includes a first electrical busway section, a second electrical busway section, and a busway joint. The first and second electrical busway sections are disposed longitudinally offset from each other. The busway joint couples the first and second busway sections. The busway joint includes a first assembly coupled to the first busway section, a second assembly coupled to the second busway section, a plurality of conductors coupled to the first and second assemblies, a first movable brace coupled to the conductors, and a first brace locator coupled to the movable brace. The first and second assemblies move relative to each other between a collapsed position and an extended position. The first movable brace moves longitudinally along a length of the conductors. The first brace locator locates the first movable brace at a first position when the first assembly is in the extended position.
