Equipotential Bonding

[EddieB]

Hi all
I was looking for the section in the red book that gives the size of the water and gas services bonding cable. I know for domestics it's 10mm and 16mm main earth to the consumer unit but what table actually gives it to you the sizes.

I think it is table 54.8 on pg 134 of the red book you are after.
