ABSTRACT:
A lever-type handle for operating a racking mechanism and providing an interlock for a cabinet enclosing electrical equipment. The handle is comprised of two sections which are linked together by a throughbolt. A cover assembly retaining and enclosing a portion of the handle is provided with an opening oriented so that the bolt is only accessible when the handle is in an "on," or energized, position. By removing the through bolt the handle sections are disengaged so that one portion can be moved to a non-locking position and access gained to the cabinet interior.
