How does a cartridge fuse work?
Cartridge fuse works according to the principle of conductor melting and must be replaced with a new one when it is blown. When the wire melts, it becomes an open circuit, and no electricity flows. Cartridge fuses are replaced inside a holder. This is called a cartridge fuse carrier or fuse holder.
How does a cartridge fuse provide safety?
Current is the amount of amperage flowing through a wire or circuit, and every wire or circuit has a specific maximum current rating. When this current is exceeded, the OCPD shuts off the power to the circuit, preventing fires and other serious hazards.

Why are four screw in fuses not working?
The four screw-in fuses are for branch circuits. If only a few of your lights or receptacles don’t work, it’s probably because one of those fuses is open (blown). YOu can usually tell which is bad because it will have a blackened face, or (for the time delay type) the spring inside will be short rather than stretched out.
