    The SANS 10142 regulation 6.1.11(pasted below ) does not allow you to use flexible cords in an installation would be the easy answer

    The reason behind it I have always understood the insulation is not the same standard as T&E .
    There are flexible cords that are made to higher standards and could be acceptable in the future.But for the time being 6.1.11 applies


    6.1.11 Flexible cords shall not be used as part of the electrical installation,
    except where
    a) required by the relevant product solely for termination or connection of
    moving parts,
    b) specified in the product standard,
    c) used as single cores in conduits,
    d) used in an authorized wiring system (see 3.5), or
    e) needed for the connection of luminaires, provided that each connection is
    limited to one luminaire and to a maximum length of 3 m.

  3. Thanks given for this post:

    Flexible cords can be manufactured to far higher specifications than installation cable such as twin and earth, I think the big problem with flexible cords is that they're fine stranded wiring which requires some type of ferrule when it's terminated. Most terminations in electrical accessories and in DB's are designed for the solid type conductors or coarse stranded type conductors which are found in installation cables and aren't suitable for fine stranded wiring.

    i wouldnt say db boards are not suited for fine stranded wire. a bootlace ferrule works well.
    maybe its to do with the greater chances of it being abused in an installation. the green yellow earth wire being used as live conductors. i think from 6mm up you can use flexible cable anywhere in an installation.
