If an appliance develops a fault, the current may become too high. This would cause the wires in the flex to get hot and might cause a fire or damage components within the appliance. Every three pin plug has a fuse connected to the live wirer.?????A 13A fuse with a low melting point wire.The fuse has a thin piece of wire inside it, which is the weakest link in a circuit.??????
Bcz. The fuse prevent the wire not to burn or melt as curret is more that is why fuse is connected the the live wires , when current is more then the fuse will get starting heating up and at the stage it will get melt down then it breaks the circuit and prevent the wires
Nuteral wire
