Here, if you connect live with neutral through a wire, resistance of wire is negligible so it causes short circuit. If a fault occurs where the live wire connects to the case, the earth wire allows a large current to flow through the live and earth wires. This overheats the fuse which melts and breaks the circuit.

Will I get electrocuted if I cut a cable wire?

Can cut wires start a fire?

Can a cut cable wire cause a fire? If by ‘cable wire’ you mean Coax cable for the TV, or Internet, then the answer is no. The power/voltages in the cable are way to low to produce a spark which is usually what triggers flame.

Will rubber gloves stop electric shock?
