Hi all, I have been asked to install new electrics to a wooden lodge / chalet. It is a single storey very large building with a flat roof.
I have a few questions to ask and would be grateful of any answers.
1. Is it ok to wire in Twin and earth or should I be using LSF / LSZH?
2. At the moment it is just cladded on outside with stud walls built. I find out construction of interior walls tomorrow. If it is celotex in walls and in ceiling how do you run the wires. I know some walls are battened off with roofing batten so cables can be run down front of celotex, but what if like I have seen in the past this isn’t the case and celotex is flush with the plasterboard?
3. When running cables in flat roof how do you do it if same scenario as walls and celotex flush with the plasterboard? If I drill holes through neutral point of joist and quarter of the span in flat roof they will be where the celotex is so how can they be run?
4. They’ve asked for spotlights everywhere in celotex so the thermal barrier will be broken. In the past I’ve always asked the builder to ask building inspector and also asked 3 building inspectors myself and they don’t seem to care and say it’s fine. One inspector did say it’s good to put 25mm celotex over the hole cut out for spotlight, but never seen it done!
5. They want about 10 outside lights, but how do I do them because vapour barrier will be broken?
( I will be recommending arc protection to the install).
I like to think I am a good electrician who takes pride in his work, but nowadays nothing seems to be straightforward and I seem to spend my whole life thinking about how I’m going to do the job rather than doing the job!
I just wanted everyone’s honest opinions on what they would do in these scenarios.
Most posts of people I see on the forums tell you what not to do, but don’t help with getting over the hurdle.
Thanks to anyone who takes the time to answer.. much appreciated
