    Of course - I have never said that the cable D could be omitted, but if the CU is non-conducting there are no exposed CPs in that circuit so the definition of a CPC does not fit well.

    Sorry - I didn't mean to suggest it could be omitted - merely that it still has that function even though the need for it is further downstream (or even if there's no need for it at all at present, and it's just included on the off chance that exposed-conductive-parts are added at a later date (last paragraph of 411.3.1.1)).

       - Andy.
