Your question doesn't make any sense. Do you mean 630 mm2, in which case the fact that the conductor is square is irrelevant. Or do you mean a square with 630-mm sides, in which case it is enormous!
There is no simple answer to this question, as it depends on how the cable is installed, the number of cables involved, the type of insulating material, etc. You will need to consider these factors, then look up that information in the conductor rating tables in the Wiring Regulations which apply to your country.
1sqmm to 500sqmm size 3 core alluminium conductor cable can draw up to 2000 amps
tell me this ans
100 amp
112 amp
25 amps
what is the current carrying capacity of 4 core aluminum cable 300m long
according to manufacturers data sheet 325amps ,but plz tell me how to calculate current carrying capacity of a cable.
see cable table chart
The current-carrying capacity of a cable depends on a number of things in addition to its cross-sectional area; these include the type of conductor, number of cores, type of insulation, whether or not it is armoured, method of installation, etc. Accordingly, to determine its current-carrying capacity, you will need to refer to your national electrical code. For example, in the UK, BS 7671:2008 Requirements for Electrical Installations contains tables for all standard cable types, specifying current-carrying capacity, voltage drops, etc.
2.5 sqmm cu cable current carrying capacity is 19 amps.
It will just be the sum of the current-carrying capacity of each individual cable.
64 AMPS
25 amps
what is the current carrying capacity of 4 core aluminum cable 300m long
according to manufacturers data sheet 325amps ,but plz tell me how to calculate current carrying capacity of a cable.
what is the current carrying capasity of 16mm cable
see cable table chart
I can say it is 29 Amps.But again it depends on the cable length.The more the cable length is the less the current carrying capacity will be.
350-400Amps

The tables within Appendix 4; "Current-carrying capacity and voltage drop for cables and flexible cords." 4D1 to 4J4. For each type of cable, you will find (with a couple of exceptions) a Table A for current-carrying capacity values and following it, a Table B for voltage drop values.
