Abstract
A spout for a connection between a bus bar and a circuit breaker in switchgear includes a housing and a fixed contact. The housing is formed of insulative material and includes a tubular body having an inner cavity and a radial first ventilation opening, a base portion having a first longitudinal opening, and a fixed contact receiving portion having a second longitudinal opening. The fixed contact is formed of a conductive material, has an outer contact surface exposed through the second longitudinal opening, and forms a portion of an outer surface of the spout. A switchgear includes a wall dividing a circuit breaker compartment from a bus bar compartment, and the base portion of the spout is securable to the wall. A method of increasing heat dissipation within switchgear using the spout includes securing a bus bar to the outer contact surface, and dissipating heat through the radial ventilation opening.
