For more on marking an answer as the "Best Answer", please visit our FAQ.Here's an example. The live wire on your cooker works loose and touches the metal casing. If the casing is earthed, the breaker will trip (almost) immediately. If it's not, the breaker will trip when the casing becomes earthed (i.e. when you touch it and current starts to flow to earth through you).
Personally, I prefer the first option.
