Publication number: 20020122279Abstract: An operating handle assembly is provided having an improved handle engagement arrangement, thereby enabling the operating handle assembly to be adaptable for both human and machine interaction without the requirement of special attachment hardware. An operating handle assembly having a handle base and handle stem can accept a first handle extension suitable for human interaction or a second handle extension suitable for machine interaction. Assembly features provide for proper assembly of the handle extension to the handle stem while maintaining appropriate electrical clearances to live parts. The two part operating handle assembly, handle base with handle stem plus handle extension, provides for improved manufacturability of the host device, whereby the end-use construction of the host device need not be identified until a late point in the production cycle. The host device may be, but is not limited to, a standard circuit breaker, a rotary circuit breaker, a switch, or a disconnect device.Type: ApplicationFiled: December 29, 2000Publication date: September 5, 2002Inventors: Randall Lee Greenberg, Girish Hassan, Roger Neil Castonguay, James Lawrence Rosen, Samuel Stephen Kim, David Arnold
