    Cables running through accessories to feed another circuit.

    There was a post yesterday, can't recall the exact one. I'll start by saying I wouldn't do it and never have, there were several reasons and answers that, although they provided some sort of response, there was never any definitive proof as to whether it was against the BS 7671. Now I don't know...
