On the new sink which I just bought I am instructed that it must be earthed, certainly the sink in my utility room is so earthed - although the old sink which I just removed from the kitchen wasn't.
While I understand the legalities, I cannot for the life of me see that earthing the sink decreases risk. If someone picks up a badly earthed kitchen item with a "live" casing, touching the earthed sink will give a good path to ground through the body. If the sink was insulated from earth, there would be no such path.
What's the logic of this earthing, just out of interest?
