What Happens When a Fuse Blows
Most homes built after 1965, as well as older homes that have updated electrical services, have circuit breakers that control the electrical circuits in their homes. But in older homes that haven't been updated, the electrical circuits are protected and controlled by fuses located in a central fuse box. These devices serve the same function as circuit breakers to protect against circuit overloads and short circuits, but rather than resetting them when they "trip," you must replace fuses when they burn out ("blow").
