Hi. Thinking of setting up on my own and planning to join one of the "clubs". The job i have chosen for the assesment is a consumer unit change. The earthing arrangement is TNC-S and the Equipotential bonding is present to gas and water using 6mm cable. My question is this, do i have to upgrade the bonding to 10mm or do i put a comment on the EIC. I have looked in the regs book but can not find anything on it.
Cheers Murphy.
