The circuit interrupting device has an actuator configured for rotation about a switching axis to switch the device between ON and OFF conditions. The apparatus further includes a front access hub supported for rotation about an axis orthogonal to the switching axis. A handle is coupled to the front access hub to rotate the front access hub about the orthogonal axis. A mechanism interconnects the front access hub with the actuator to rotate the actuator in response to rotation of the front access hub. ## Claims ### Claim 1 An apparatus comprising: a cabinet; a circuit interrupting device installed in the cabinet, the circuit interrupting device having an actuator configured for rotation about a switching axis to switch the circuit interrupting device between ON and OFF conditions;
