    Morning! Would someone please mind checking the big brown book for 1.5mm flat sheathed cable, ref method B, CCC? Page 456 from memory. Only have the blue book in the van, which lists refs A and C but not B. Voltage drop is ok, as is Zs. Thanks! :)

    what reference method?

    T/E clipped direct to brick. however, kingspan backed board is to be fitted so insulation direct onto cable. my thoughts are 102 as cable is touching wall, but not the inner board as described in BS7671.
