Question
What kind of appliance casing requires an earth wire?
Solution
An earth wire is required for the casing of appliances that are made of conductive materials, such as metal. This is because these materials can become live if a fault occurs within the appliance, posing a risk of electric shock. The earth wire provides a path for the electric current to flow safely away in the event of a fault. This type of appliance is often referred to as a Class I or earthed appliance. Examples include kettles, toasters, and washing machines.
