[QUOTE="ADS, post: 288185, member: 7231"] OK then. :) Bonding has nothing to do with fault current travelling down anywhere..............it is to equalise 'potentials' on metalwork, within a location, under fault conditions - i.e. so there is no 'potential difference' between two accessible pieces of metalwork. So, totally nothing to do with how fat your copper pipe is. :) But in the OPs scenario, it might do. The gas pipe comes up from the ground into a 'T' (external). One branch goes through the wall, under the kitchen floor and pops up by the cooker - where it is bonded. The other branch goes straight up the outside wall and into the bathroom............so it might introduce a different potential into the bathroom. Like I and a couple of others have said - the only way to know for certain if it's extraneous or not is to test it - if it's extraneous, then it requires bonding. [/QUOTE]
