Abstract: A switchgear assembly is provided with an integrated arc flash venting system. The switchgear assembly comprises a circuit breaker section including an arc flash vent stack having blow open flaps disposed on a switchgear roof to exhaust arc flash gases and contaminants away from a front of the circuit breaker section, towards a rear of the circuit breaker section and a top of the circuit breaker section. The circuit breaker section includes a circuit breaker compartment having a back wall with a back vent opening for the passage of all the arc flash gases and contaminants. The circuit breaker section further includes a bus compartment. All of the arc flash gases and contaminants pass through the back vent opening in the circuit breaker compartment and into the bus compartment which forms a single pathway for channeling all of the arc flash gases and contaminants to the arc flash vent stack.
