Discuss Gas & Water bonded to 1 x 10mm cable? in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net

Welcome to ElectriciansForums.net - The American Electrical Advice Forum

I have read this previous thread (2012):
gas and water bond, can i use 1 x 10mm cable? - https://www.electriciansforums.co.uk/threads/gas-and-water-bond-can-i-use-1-x-10mm-cable.66838/
I have a situation where the gas and water enter the building parallel to each other. The gas meter is some 3 meters away from the entry point. Is the above thread still within regs? Do I also have to provide a 10mm earthing bond to the customer side of the gas meter or is entry point acceptable? o_O

1 x 10mm cable to both gas and water is absolutely fine as long as it is continuous.
 
There is actually no Regulation in BS7671 stating it must be continuous so you can use a single conductor for both services continuous or not.

regulation number please if you can

Continuous as in A to B, not one complete piece of cable . A well made interconnection between the two bonds is no more at risk than any other high integrity joint.

You do realise Pete that @westward10 will ask you for a reg number showing that it needs to be continuous :). I am desperately trying to find it! However, knowing his experience and knowledge level I fear there is not one :mad:

There is no reg as far as I can remember stating it must be continuous throughout its run.

There isn’t one....I believe it’s written in one of the guidance note books but obviously it’s only guidance. Its obviously considered best practice Incase a clamp is taken off by a wet pants etc but from a regs point of view it’s perfectly acceptable.

He's right Pete Q & A of the Day – What regulation for bonding adjacent gas and water supplies? - https://www.voltimum.co.uk/articles/q-day-what-regulation-bonding :(

He's like Davesparks, hardly ever wrong, but we'll get them one day!! I've only ever managed to prove Davesparks wrong once and that was on a technicality:D

Think about it Pete if you had a distribution circuit supplying an out building that had extraneous conductive parts. The earthing conductor in the distribution cable is of adequate size to be used as a bonding conductor as well as functioning as a CPC. This is then connected to the earth marshaling terminal at the far end and from this EMT, bonding conductors were run to water and structural steel separately, they would still be using the same single conductor from the EMT to the MET.....There really is no difference in using a bonding conductor from the MET to both gas and water.

I agree, But that could be true of any connection.
