Question

Describe the hazard to the engineer if there is no earth wire​

Answer 1

Explanation:

Without the earth wire, if a fault occurs and the live wire becomes loose, there is a danger that it will touch the case. The next person who uses the appliance could get electrocuted . ... As a result, the casing cannot give an electric shock, even if the wires inside become loose.

Earthing is used to protect you from an electric shock. It does this by providing a path (a protective conductor) for a fault current to flow to earth. It also causes the protective device (either a circuit-breaker or fuse) to switch off the electric current to the circuit that has the fault.
