Abstract
Disclosed is a tool for removing and installing fuses in metal-enclosed switchgear. The switchgear includes one or more fuses and one or more isolating switches and operating mechanisms for isolating the fuses from a high voltage supply circuit. The fuses are mounted between disengageable contacts that connect the fuse between the supply circuit and a load circuit. Access ports are provided through a front panel of the switchgear and are aligned with the fuses for providing access to the fuses. A tool receiving receptacle is mounted on the front panel around the access ports. The tool comprises a hollow metal housing having a hollow interior and having a flange on one end for being received and retained by the receptacle. The receptacle aligns the hollow interior of the metal housing with the access port, and makes grounding connection from the housing to the front panel. The tool also comprises an operating portion including a handle mounted on one end of an insulator. Mounted on the other end of the insulator is a fuse engaging arrangement that engages the end of the fuse when the engaging arrangement is placed against the end of the fuse and the operating portion is rotated 180.…
