Fuse cutout

Cutout (left) attached to a feeder line (connection at the right not shown). The lower wire goes to the transformer

A set of pole top cutouts protecting a transformer on a 12.47 kV distribution line. One fuse is blown and the white tube is hanging down

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".
