Abstract
The present technique, applicable to low voltage, medium voltage, and high voltage MCCs and other power management systems, provides for substantially containing and directing an arcing fault and resultant ionized gases within a stab enclosure or housing disposed in the MCC. For example, the stab housing may have reduced stab-openings at the power bus interface to diminish the potential of an arc flash (and ionized gases) from reaching the power buses. Furthermore, phase-to-phase isolation barriers may be employed within the stab housing to reduce the potential of an arcing fault going phase-to-phase. Moreover, to reduce arc flash damage within the MCC, the walls and barriers, including walls around the stabs, within the housing may be configured to direct the arc on a preferred path to a desired location within the housing to extinguish the arc in less than 0.1 second or 6 cycles, or even less than 0.033 second or 2 cycles.
