Abstract
A device for diverting energy away from an electrical arc flash is provided. The device comprises an arc source configured to create a second arc flash, a plasma gun configured to inject plasma in proximity of the arc source in response to the arc flash, an arc containment device to house the arc source and the plasma gun, an exhaust port configured to route exhaust gases out of the device in a first direction, and an exhaust duct coupled in flow communication with the exhaust port, the exhaust duct comprising a substantially hollow tube including a first tube portion and a second tube portion, the first tube portion coupled in flow communication with the exhaust port, the second tube portion defining an exhaust vent and coupled in flow communication with the first tube portion to route the exhaust gases out of the device in a second direction.
