Just wondering if someone could give me some advice? I live in a victorian terrace and my meter & CU are upstairs in one of the bedrooms. The mains comes in from the outside wall straight in to a henly block. The cable is not a std SWA more like a figure of eight type. The thing is, there is no earth comming from this cable. The consumer unit has two earth cables entering it, one larger than the other and they both come from under the floor boards. There is no earth connection to either the gas or water incomming feeds that I can see. Where could the earth be comming from? the house was re-wired before we moved in and we cannot find out who by. Any thoughts?
