Abstract
An over running clutch assembly for an electrical switching apparatus is provided. The over running clutch assembly includes a sprocket and a hub assembly. The hub assembly is rotatably coupled to the sprocket and structured to rotate in a charging direction relative to the sprocket. The sprocket is fixed to a motor shaft. The hub assembly is structured to be disengagably fixed to a cam shaft in the charging assembly. A manual charging handle is also coupled to the cam shaft and is structured to rotate the cam shaft in a charging direction. In this configuration, an operator may charge the closing springs of the electrical switching apparatus using either the handle assembly or the motor. When the handle assembly is used to charge the closing springs, the cam shaft causes the hub assembly to rotate over the sprocket. Thus, the rotation of the cam shaft is not transferred to the motor. When the motor is used, the motor turns both the sprocket and the hub assembly. The hub assembly transfers the rotational force from the motor to the cam shaft.
