A circuit breaker panelboard has a rear housing that mounts a plurality of circuit breaker modules arranged in a pair of spaced columns. Each module has an actuator associated with it and the plurality of actuators are also arranged in a pair of spaced columns. A front cover is releasably attachable to the rear housing for enclosing the circuit breaker modules and associated actuators. And an improved circuit breaker actuating assembly is coupled to the circuit breaker actuators and to the front cover for facilitating manipulation of the actuators from the exterior of the front cover. The actuating assembly includes operating members and linking members. The operating members of the first group are disposed in a first pair of columns aligned with the pair of columns of circuit breaker actuators and are provided in directly coupled relationships with first alternating ones of the circuit breaker actuators in the columns. The operating members of the second group are disposed in a second pair of columns respectively displaced laterally outwardly from opposite sides of the pair of columns of circuit breaker actuators and are provided in indirectly coupled relationships with second alternating ones of the circuit breaker actuators in the columns. The linking members are formed into first and second groups which extend between and interconnect the second alternating ones of the circuit breaker actuators in the columns and respective ones of the operating members of the second group disposed in the second pair of columns so as to provide the indirectly coupled relationships therebetween.
