A blown fuse may be discolored, cloudy, or have a melted or broken metal piece inside. With the main power still off, unscrew the blown fuse and remove it. Never replace a blown fuse with one of a higher amperage , which can be dangerous or can cause damage to your electrical panel wiring.
You can take the blown fuse to a hardware or home store for help in getting an exact replacement. Screw the new fuse into the same electrical panel socket. Never put anything other than a fuse into the fuse socket or holder.
Now, restore the main power to the electrical panel. If the fuse is fine after reconnecting the main power, plug in a couple of electrical appliances or turn on some lights in the electrical zone controlled by the new fuse.
