Evening rob ,don't know the legal side of this ,anyway for what it's worth ,one of my mates came around this afternoon,he had a visit from an electrical inspector from the local council thismorning , He basically condemned the ring main in his workshop,what he said was that all electrical cables from the floor up to a certain height had to be in conduit.the reason being that if any metal fell on the cable and damaged it ,it would then be live ,that's the reason he gave him , He said it would take about 3 to 4 weeks before his report would be acted upon ,then they would send someone out to see if he had put in the conduit,if he doesn't comply they will cut off his supply to the workshop ,then he would have to get some sort of certificate before they would reconnect the power to his workshop.one of the other things the guy pointed out to him was that if he had a fire and put in a claim to his insurance company,it could be void if he hadn't complied with local building regs . Hope this helps to make your mind up . |

Hi Rob and all! I have been pondering the self same question, as am about half way through taking all the wiring out of my ceilings so I can insulate and board them, and not need to be in to make the inevitable additions. What I am going to do is dry line and insulate the walls in the workshop with 1" x 2" treated timber, and 2" of jablite, and I shall have a 3" deep trunking round the walls at ceiling level with seperate narrow covers on, but constructed with timber as part of the dry lining process. I will then drop out of the edge of the extra inch with 20mm black pvc conduit. JB3CX, where are you in the world, it is not like council inspectors to pop round unannounced or uninvited. Having said that, it makes perfect sense, to protect cables which are in the working area, and PVC conduit looks good, and is easy to fix, and quite cheap. Phil |

Hi there, Phil, Before you pay out on your insulation, I suggest that you research the relative flammabilities of Jablite vs Kingspan/Cellotex. Jablite is, as far as I know, a trade name for polystyrene foam. I remember that, at one time, there was a fashion for applying expanded polystyrene tiles to ceilings. That practice fell out of fashion when it became evident that, in the event of a fire, the tiles melted and took light and dropped burning molten polystyrene on to whatever was below! I'm not saying that Kingspan/Cellotex insulation is fireproof - I'm just recommending you to research the matter and to make an informed decision. |

Also polystyrene in contact with pvc insulation has a long term reaction. It came to light when people laid insulation in lofts on top of existing cables - the two bond together so one or the other is dissolving the other or one :scratch: |
