Abstract
An electrical switching apparatus for housing a pair of opposing circuit breakers each circuit breaker of the pair of opposing circuit breakers having an opposing end face including an exhaust vent disposed thereon is disclosed. The electrical switching apparatus includes a panelboard to operatively support the pair of opposing circuit breakers to define a gap therebetween, and an insulative barrier to be operatively disposed in the gap. The insulative barrier includes a first cantilever wall member arrangeable to define a first plenum region having a first cross sectional area, and a second plenum region having a second cross sectional area. The insulative barrier is operative to deflect in a first direction to thereby increase one of the first and second cross sectional areas in response to a venting of ionized gases from one circuit breaker of the pair of circuit breakers.
