Why should a fuse be used in the household electricity meter? What would happen if you replaced the fuse with copper wire?
You can use it instead. Only when a short circuit is burned out, the switch will not pick off, easy to cause fire. Because the melting point of copper wire is much higher than that of tin.
In case of short circuit, the fuse will fuse in time, cut off the circuit and protect the electric appliance from burning. Copper wire if the fuse current requirements are large, not easy to fuse, and to protect the role of electrical appliances.
Short circuit fuses fuse, copper wire sometimes burns, poor quality wire will fire, copper wire can not replace the fuse.
