摘要： A mounting base or a riser base for a switchgear is provided with side interior openings to provide an internal arc pathway through which arc gasses or plasma are safely discharged to an outside air. The mounting base includes a front wall having a first end and a second end, a rear wall having a first end and a second end, a first side channel connecting the first end of the front wall to the first end of the rear wall, a second side channel connecting the second end of the front wall to the second end of the rear wall, and forming the mounting base having a central open area in a first section of a switchgear that is adjacent a second section of the switchgear. The mounting base further includes at least one opening in the first side channel for the passage of an arc from the first section of the switchgear to the second section of the switchgear, and thereby forming the mounting base with the internal arc pathway.

摘要： 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.

摘要： A power distribution assembly includes a first conductor having a first conductor end and a first shape in cross-section and a second conductor having a second conductor end and a second shape in cross-section. A splice couples the first conductor end to the second conductor end. An insulative boot has a first opening of the first shape, wherein the insulative boot encompasses the first conductor end. The insulative boot also has a second opening having the second shape, wherein the second opening encompasses the second conductor end. The insulative boot has a cavity between the first end and the second end, wherein the cavity is configured to encompass the splice.
