New way to wire lighting circuits

Former Community Member
Former Community Member
Hello,


Does anyone know anything about a new rule to wire lighting circuits so that they have a live, neutral and earth running the full length of the circuit? I heard something about this last year but cannot pinpoint it in the 18th Edition Regs.


Apparently, a light now has to be wired so that the neutral running to the switch is USED as a neutral, and not as a switched live.


Anyone else heard of this?


Thanks,


David

    Indeed, not a requirement, just permitted.
    559.5.1.208 Consideration shall be given to the provision of the neutral conductor, at each switch position, to

    facilitate the installation of electronic switching devices.


    Actually it's always been permitted,  as there are some layouts of building where to do anything else makes no sense.

    If you like you could have a socket at the light switch, albeit one of limited current capacity.


    There are some pretty daft sections in that bit of the regs. actually.


    Try this for a giggle.
    ...the connecting device shall be:

    (i) terminals according to BS EN 60998, or

    (ii) a device for connecting a Juminaire (DCL) plug according to BS EN 61995, or

    (iii) an installation coupler according to BS EN 61535, or

    (iv) supporting coupler (LSC) plug according to BS 6972 or BS 700 I, or

    (v) a male connector (plug) of a plug-in lighting distribution unit according to BS 5733, or

    (vi) another suitable and appropriate connecting device.


    Well it strikes me that if you have (iv) the other lines could safely be deleted,

    unless they are suggesting they are somehow  permitted but 'unsuitable'
