Earthing my house ,
There is a 16mm2 earth cable from my intake supply to the consumer unit.
I have ran and connected 2 10mm2 earth cables(one to the gas meter) and (one to the mains water pipe as close as i can get to the point of entry.
What size cable do i need to cross bond my pipe work (taps) etc still 10mm2 or can i drop to 6mm2.
Thanks
Nigel.
