I am in the process of building a garden office/workshop and although I intend to get an electrician to install the power and light circuits, I would like your advice on what options are permissible for concealed power circuits -
The studwork is 44x97 sheathed outside with 12mm ply + cedar shingles and will eventually be rockwall insulated and lined with probably 8mm ply, so I can't see how 2.5mm T/E (or whatever after derating) would satisfy the 50mm clearance requirement (safely inside and out).
As I do not want to have any surface conduit I'm concerned that whilst I may know where the cables run, others may not and certainly from the outside the risk of e.g. nail penetration high.
Would SWA within the void satisfy the 'mirror image' issue raised in http://web.archive.org/web/20061110111450/http://www.niceic.org.uk/downloads/concealedcables.pdf
i.e. I am assuming that the location of the 'accessory/switchgear' would not be possible (unless you measured really careful) from the outside wall
Ultimately it will be my electricians decision on how to address this, but am interested to understand what other options there may be,
Cheers
