ABSTRACT:
This invention relates to a power distribution arrangement in a large metal enclosed switchgear assembly. Electric current is carried from a source to a group of circuit breakers in the switchgear enclosure by means of two separate sets of bus bars to produce a ring bus effect. Vertical bus is connected to the source bus to carry power to the line side of the circuit breakers in the assembly. The load conductor of each circuit breaker returns via an aperture in the line bus and passes therethrough, but does not contact the line bus. Both sets of bus feeding the circuit breakers are mounted so as to have their major surfaces parallel.
