i didnt expect anything less that this reply Apache!They must have updated the pagethis is the link
the 17th did not ammend that regulation?But if you read it closely it was written for the 16th edition.
Not quite sure what this statement means?CSA is given but capacity is different for steel and copper

Fine, but just out of curiosity what exactly is the current carrying capacity, in ampere,s of the steel wire sheath for the various sizes?I thought that the point of using K was to establish the correct CSA for current carrying capacity.
does this not involve money changing hands?If you join the IET forum, you can ask John Peckham for his updated version.
Not that I'm aware of.does this not involve money changing hands?
There are two parameters to consider. The thermal withstand, which is what the k formula is intended to be used for.Fine, but just out of curiosity what exactly is the current carrying capacity, in ampere,s of the steel wire sheath for the various sizes?the link gives the CSA but you would need also the resistivity of the steel to get the capacity, would you not?
