Abstract
A drive shaft extension assembly is provided for an electrical switching apparatus which is removably disposed in a cassette. The electrical switching apparatus includes a levering assembly with a drive shaft. The drive shaft extension assembly includes a housing assembly, a shaft extension including an elongated body, and a racking gear. The shaft extension is structured to be coupled to the drive shaft in a fixed orientation, thereby increasing the width of the levering assembly.
