Hi,
Anyone come across a metal enclosure/cabinet that houses the mains incoming supply and consumer unit?
Its in a 60's built block of flats. Is the earth for these types of supply from the gland around the incoming and therefore the whole of the metal enclosure which is sunk into the wall is the earth?
