A ground fault circuit interrupter (GFCI) is a device that
shuts off an electric power circuit when it detects that current is flowing
along an unintended path, such as through water or a person. It's there to
protect people from electrical shock, so it is completely different from a
fuse.
A GFCI monitors the amount of current flowing from hot to
neutral. If there is any imbalance, it trips the circuit. GFCIs are generally
installed where electrical circuits may accidentally come into contact with
water. They are most often found in kitchens, bath and laundry rooms, outside
or in the garage. GFCIs will fail to work safely and correctly if they are wired
improperly.
