http://www.kevinboone.com/cableselection_web.html is reasonablly good advice though its interpretation of the regs is a little pessimistic.

Ah, sorry - these are next week's numbers

http://www.tlc-direct.co.uk/Technical/Charts/VoltageDrop.html has an even more simplistic calculator. It rather depends why you want to know the calculation - if its a complicated situation it probably needs more sophisication than either of those links.

formula of cable size calculation

Ok.

Iz = It x Ca x Ci x Ct x Cg x Cr

Oh and don't forget to check that volt-drop and EFLI are OK as well.

Happy now?
