I have been to different areas of sites to earthing in bathrooms and each area is different.With a dual rcd you dont have to cross bond in the bathroom,with a split load board you do this is between hot and cold under bath panel, under the sink hot and cold plus radiator.I have also seen 4mm earth off the light in the bathroom linked to the shower,under the bath panel hot and cold with a dual rcd board.I have stated all this because im getting a little confused of how to earth depending on the board used etc could you help?
