Fuse is a device that is a safeguard to all of our electrical appliances. They are made up of special material which melt quickly and break when a large electric currents passed through it. If the electrician does not use proper fuse wire, instead he uses any ordinary electric wire as fuse, it increases the risk of overheating of wires due to flow of excessive current. It may lead to short circuit in electric equipment and these appliances may catch fire. It is advised to use standard fuse wire or MCBs to prevent electrical accidents
No, because fuse is made of lead wire which has a very low melting point. A fuse wire melts quickly and breaks when large amount of current passes through the circuit. If the electrician replaces a fuse by a piece of ordinary wire (which has high melting point) it increases the risk of overheating due to flow of excessive current. This may lead to short circuit and fire.
