ABSTRACT:
The present invention provides an assembly and method for mounting a plurality of circuit breakers for electrical and mechanical connection to a bus bar in a module of a distribution board. The mounting assembly includes each circuit breaker having a housing which is defined by a contact end for connecting to the bus bar, a mounting end for securing to the cell of the distribution board, and side panels extending therebetween. Each housing has a top surface and a bottom surface. The connect end of each housing has a bus bar terminal for connecting to the bus bar. At least one spacer is located between at least two of the circuit breakers. The spacer has a predetermined width between the side panels of adjacent circuit breakers. The spacer width is sufficient to spread the circuit breakers apart from each other and align the bus bar terminal of each housing with the busbar. A bracket is also provided with spacing flanges having a predetermined width to extend between the side panels of the circuit breakers sufficient to spread the circuit breakers apart from each other and align the connect ends of the circuit breakers with the busbar. Preferably, the mounting assembly pivotally mounts a line terminal within the housing of the circuit breaker permitting the slot of a contact jaw to move freely in a direction perpendicular to the busbar.
