caption_attribution_description: English: A fuse cutout at a service drop on a single-phase overhead power distribution line. The power line, supported by the insulator at the top of the pole, is visible in the background. The service drop is a feed line attached to the power line which feeds power to a single residence. The fuse cutout (device in foreground) is a combination fuse and switch which allows the transformer and residence to be disconnected from the power line in the event of an emergency. It consists of a fusible metal bar supported between two terminal clips by an insulator. If a short circuit occurs, the bar will melt and pivot open, giving a visual indication of the trouble. The sevice drop can also be manually disconnected from the line by electrical lineworkers while the line is energized, by pulling the device open using a long insulated fiberglass stick with a hook on the end, called a hotstick.
context_page_description: In electrical distribution, a fuse cutout or cut-out fuse is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to melt, disconnecting the transformer from the line. It can also be opened manually by utility linemen standing on the ground and using a long insulating stick called a "hot stick".
