  • Patent number: 9368945
    Abstract: Methods and systems for minimizing exposure to live parts in a panelboard allow safe insulation and removal of a circuit breaker or other electrical devices from the panelboard. The methods and systems provide an isolation assembly for the panelboard that isolates and prevents contact with energized portions of the circuit breaker as well as the conductors in the panelboard. The isolation assembly covers up the energized part of the circuit breaker, including the line terminal extending from the circuit breaker, and any accessible portion of the conductors in the panelboard. Additionally, for bolt-on type circuit breakers, the isolation assembly replaces the bolts or screws typically used to fasten the line terminals to the conductors in the panelboard with standoff screws that insulate metal screwdrivers and similar tools from the energized part of the circuit breaker.

  • Patent number: 9338866
    Abstract: Methods and systems for limiting damage caused by arcs in bus stacks provide an arc transfer feature on each side of the bus stack. The arc transfer feature captures any arcs forming near busbar connection points and transfers the arc away from the busbar connection points to the interior of the bus stack. Phase barriers along the length of the interior of the bus stack then direct the arcs toward the end of the bus stack. At the end of the bus stack, a bus end interrupter receives and extinguishes the arcs.
