Table showing max Zs by 7671 & 80% values

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.
