Metal Cable Ties

Stuart Urban
I have been told that "BS 7671 States that the use of metal cable ties is required for cables of certain gauges". Is there anything somewhere like this in the regs?

    Refer 521.10.202

    Wiring systems shall be supported such that they will not be liable to premature collapse in the event of a fire. 




    NOTE 1: 
    Wiring Systems hanging across access or egress routes may hinder evacuation and firefighting activities. 

    NOTE 2. 
    Cables installed in or on steel cable containment systems are deemed to meet the requirements of this regulation. 

    NOTE 3: 
    This regulation precludes, for example, the use of non-metallic cable clips or cable ties as the sole means of support where cables are clipped direct to exposed surfaces or suspended under cable tray, and the use of non-metallic cable trunking as the sole means of support Of the cables therein. 

    NOTE 4. 
    Suitably spaced steel or copper clips, saddles or ties are examples that will meet the requirements of this regulation.

    Yes thanks, and this:

    “522.8.4 Where conductors or cables are not supported continuously due to the method of installation, they shall be supported by suitable means at appropriate intervals in such a manner that the conductors or cables do not suffer damage by their own weight.

    522.8.5 Every cable or conductor shall be supported in such a way that it is not exposed to undue mechanical strain and so that there is no appreciable mechanical strain on the terminations of the conductors, account being taken of mechanical strain imposed by the supported weight of the cable or conductor itself.”
