Abstract: A bus bar arrangement for electrical equipment has at least one bus bar and a shroud. The shroud provides a fault free interface for personnel working with the electrical equipment. First and second shrouds mounted on opposing ends of the at least one bus bar surround a substantial portion of the at least one bus bar. The shroud provides a connection surface for the connection of a wide variety of circuit breakers thereon. The shroud provides protection against intruding objects and ease of connection between circuit breaker contacts and bus bar assemblies of electrical equipment.

Abstract: A ventilation system for switchgear has at least one chimney mounted to the roof of the switchgear enclosure. The at least one chimney has a flap mounted thereon for relieving pressure, hot gases, and particulate matter generated during an arc flash. The chimneys have grates in opposing side walls for ventilation of the switchgear. Under certain conditions, the grates allow the release of pressure below the threshold for raising the flaps. The flaps elevate when gases travel between the enclosure and an internal volume of said at least one chimney.
