I'm looking at this from an electrical perspective, but I am interested in the view of a Gas Safe engineer - hence posting here.
BS6891:2005 8.16.2
Where installation pipes are not separated by electrical insulating material, they shall be spaced as follows: a) at least 150 mm away from electricity meters and associated excess current controls, electrical switches or sockets, distribution boards or consumer units; b) at least 25mm away from electricity supply and distribution cables.
BS7671:2008 (the wireing regulations) dose not have a reciprocal clause, but the on site guide does mention it. "Seperation of at least 25mm to be provided for domestic pipework up to 35mm. For pipework over 35mm then 50mm separation is required. The separation distance can be reduced if the gas pipe is PVC wrapped or a pane of insulating material is interposed."
I'm proposing to run several electrical cables past an existing 22mm copper gas pipe. I obviously don't want to cause the existing gas installation to be non-compliant. Ideally I also don't want to relocate the existing gas pipe.
I think that the sensible thing to do is use PVC conduit. This would bend around the existing gas pipe. PVC is electrically insulating so am I correct in thinking that its okay for PVC conduit carrying electrical cabling to touch a gas pipeline?
If I turned the question on its head. Would any gas safe engineer be comfortable running a 22mm copper gas pipe such that it touched or had minimal clearance from a PVC conduit?
