Hi, I wonder if anyone can clarify this. There's an electrical water heating appliance in the loo. As you can see in the picture in the link below there's an earth symbol above a screw next to the power cable. Presumably the appliance is earthed through the main cable so does anyone know what this extra earth is for? Supplemental bonding perhaps?

Many thanks for any ideas.
