    What happens when current flows through the earth? Does it trip?

    Supposing I fit a metal light fitting, and I do a terrible job - and the live comes out from the terminal screw and hits the fitting, but it's well earthed - current will flow through the earth cable (hopefully) providing a circuit with less resistance than if I touch it.
