Reference Methods

Wondered what installation reference method people might be using for a T&E cable on a masonry wall that is then covered with plasterboard, ie a typical dot and dab affair. I think "C" is correct as all installation methods involving a cable in contact with a wall and NO insulation map to reference method "C". Wouldn't think the plasterboard or covering the cable with capping would make any difference. I raised the question due to seeing A,B, & C on various other contractors certs.

    I agree with C - see installation methods 57 and 58 in Table 4A2.


    Now how about T&E which has been clipped to the underside of the floor above, or web joists with 4" of sound-proofing laid on the ceiling plasterboard? (Wet underfloor heating so at least 50 mm from both surfaces.)
