The picture shows the earthing of my consumer unit. There are 7 strands of bare wire approx 1 mm diameter each. I guess this is not an acceptable earthing method. How can I upgrade that? Do I just use 16mm squared green/yellow? Do I just bolt the new earth lead to that springy strip (where the individual wires are now). Or do I need to clamp it around the incoming metal sheath? All help appreciated. Steve.
