A 240 sq. mm. cable has a diameter of
d=square root of 4A/3.14
d= 2(square root of A/3.14)
= 2(square root of 240/3.14
=17.48 mm.
Therefore your cable has a capacity of only 515 amperes in free air. If installed in a duct with three conductors your conductor will have an ampacity of only 350 ampers.
Alternative AnswerThe answer is not straightforward, because it depends upon various factors such as the material from which the conductor is manufactured (copper or aluminium), the type of insulation employed, and the configuration of the cable (how many conductors), installation method, etc.
An Appendix to BS 7671:2008 Requirements for Electrical Installations, lists cable types according to these various factors, and specifies their current ratings.

What is the current carrying capacity of 1 sq mm to 400 sq mm above?
The current carrying capacity of a conductor depends on various factors such as the material, temperature, and installation conditions. Typically, for copper conductors in free air, the current carrying capacity ranges from around 11 amps for 1 sq mm to 450 amps for 400 sq mm. However, these values can vary depending on the specific application and standards being followed.

How can calculate the current capacity of 2.5 sq mm wire?
You don't calculate the current-carrying capacity, you find out from the appropriate Tables in your country's wiring regulations. In the UK, this is BS 7671:2008 Requirements for Electrical Installation.The reason you must do this is that the current-carrying capacity of a cable depends on the conductor type, number of cores, the type of insulation, the method of installation, etc. Allthese factors are taken into account in these Tables.For a 2.5-mm2 copper cable, the current-carrying capacity can vary from around 22 A to around 36 A, depending on the factors described above.
