    Hi,

    I need to earth a replacement faceplate to a steel back box in the wall.

    Should I use a 1mm, or 1.5mm sleeved cable for the job?

    Thanks

    Either will be fine as long as it's green/yellow wiring or sleeved that colour.

    I will go out and buy a metre of 2.5mm t&c and sleeve it yellow and green.

    I just want to be safe.

    Thanks

    The earth in the 2.5 is actually 1.5, but 1.5 will be better than 1mm. If you use 2.5mm that may be too big to fit in the switch earth terminal

    Hi,

    Sorry I didn't explain it well.

    I meant I will go out and purchase a metre of 2.5mm T&C so that I get the 1.5mm earth.

    Thanks.

    Seems you might be safer leaving it alone.

    If your spleen ruptures and needs removing would you pick up a knife or a spoon from your local shop to remove it?
