The fuse bypass jumper of the present invention bridges the upper and lower fuse terminals of a high-voltage transmission line cut-out box so as to bypass the fuse element. The jumper comprises lateral upper and lower arms connected by a longitudinal jumper bar. The jumper arms and bar are made of a heavy gauge conductor rated for at least 100 Amps. With the jumper in place, the fuse element can be opened, removed and/or replaced without interrupting the transmission line circuit through the cut-off box, since the jumper now provides a bypass around the fuse. Since the bypass conductive path constitutes a heavy gauge, high-amperage bar conductor, this jumper can carry a much larger current load than flexible wire-based jumpers.
