How to Change a Fuse
Disconnect lamps and appliances in use when circuit went out.
Make sure your hands are dry; stand on a dry board or rubber pad, if possible. Open main switch, or pull-out section of panel labeled "main" in the service entrance, to cut off current while working at the branch circuit box.
Identify the blown fuse. When a fuse blows, the transparent section becomes cloudy or blackened.
Replace the blown fuse with a new one of proper size. The smaller sizes screw in and out just like light bulbs. If the blown fuse is a cartridge type, located in the pull-out section. It can be removed and replaced by hand pressure.
Close the main switch, or replace pull-out section, to restore service.
Throw away the blown fuse
