    Flexible cords and HO7RN-F for fixed installations

    I read carefully BS7671, 17th ed., 521.9 and guidance note 1, Table F3 and F5, and no where does it say that flexible cords, such as HO7RN-F can not be used for fixed installations. I hear that was not allowed in the 15th edition but long since allowed. Am I missing something?
