I think I have to earth bond my gas meter to the supply earth at the distribution box. What size cable do I need ? 2.5mm, 6mm ?
Also can sinks, etc be bonded to the nearest earth in a socket, or do they have to be run back to the dis board as well ?
My understanding is below, however I am happy to be corrected.
10mm2 earth cable connected within 600mm of incoming supply direct to distribution board.
If you have RCDs in the consumer unit there is no longer a requirement to earth bond sinks/rads etc.
Hope that helps
Ian
We had a new consumer unit fitted and had to have a new 10 mm earthing cable because of new regs .
10mm cpc to incoming services. If you run it into gas box there will usually be enough room to get an earth Clamp on the pipe
Fine chaps. 10mm it is then. Thanks.
