    Hello all,

    Couple or so years ago someone on this site had produced a lovely document showing the above from 5A up to 100A with various protective devices.

    Not only as permitted by BS7671 but also showing 80% values as per OSG/NICEIC.

    Mine has been destroyed with water and not got another copy.

    Would any of you fine chaps have a copy that you could send me.

    Many many thans for your help.
