초록 ▼

A switchboard for mounting and supplying electrical power to a plurality of circuit breakers. The switchboard comprises a frame including a center mounting pan, and at least first and second circuit breaker mounting pans for engaging and supporting the rear end portions of the circuit breakers. The switchboard also comprises a power stack assembly mounted on the center mounting pan of the frame. The power stack assembly includes first, second and third, substantially vertically disposed main bus bar members for being connected to a source of electrical power and for releasably engaging the circuit breakers. The first main bus bar member is selectively spaced from the center mounting pan with insulator members so as to define a first ventilation passageway therebetween. The second main bus bar member is selectively spaced from the first main bus bar member with insulator members so as to define a second ventilation passageway therebetween. The third main bus bar member is selectively spaced from the second main bus bar member with insulator members so as to define a third ventilation passageway therebetween. The power stack assembly further including a channel vent cover selectively spaced from the third main bus member with insulating members so as to define a fourth ventilation passageway therebetween. Further, in the preferred embodiment the center mounting pan and the main bus bars are provided with ventilation openings along their lengths to further facilitate air flow through the power stack assembly.
