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.
