I've been helping a friend sort out some of the electric's in their house.
They are at the stage of installing a new CU, bringing all the earth bonding up to scratch and then sorting out the main earth connection.
They are installing the new CU in a new location to a bit to get more space (to the other side of the wall from the meter and current fusebox).
Main earth bonding to the incoming gas and water services is being renewed, but we weren't sure where to terminate this - run it back to the CU or install some sort of earth terminal near the meter and then run the bonding cables, and the earth from the CU back to there. The latter makes more sense to me, but I can't see it really matters.
Re the earth connection, currently the installation has been earthed via the lead mains water pipe, once the works are done, he intends to get the earth connection made properly by the supply co. The supply presumably dates back to the late 1930's when the house was built and that the earth would likely be TN-S (underground supply, in town).
Does he just make all his connections, then contact supply co. to come and make the final earth connection?
