Abstract:
A disconnect mechanism for a fuse block receiving power connections, the fuse block having a support face for fitting inside of a cabinet and holding one or more fuses accessible on a front face of the fuse block opposite the support face, the disconnect mechanism comprising:a rotary shaft communicating with the fuse block and extending outward parallel to the rear panel when the support face of the fuse block is mounted parallel to the rear panel, an outer end of the rotary shaft adapted to receive a portion of a handle mounted on a side of the cabinet, the rotary shaft rotating to disconnect the fuses from the power connections; a bolt operator extending radially from the rotary shaft to rotate therewith and providing a stop surface; a bolt movable between a lock position where the bolt may engage the stop surface preventing free rotation of the rotary shaft to connect the fuses to the power connections, and an unlock position where the bolt is disengaged from the stop surface allowing free rotation of the rotary shaft to connect the fuses to the power connections; and a finger mountable on a door of the cabinet to engage the bolt when the door is closed to move the bolt to the unlocked position; whereby inadvertent rotation of the rotary shaft may be prevented when the cabinet door is open.
