overhead conductors used for 400/230 V circuits
(OP)
What size conductors would one use for the secondary mains on a 400/230 V system? The three-phase supply transformer is 315 kVA. The application is for a western African country.

What I meant to say was what are the standard metric sizes in mm-squared that are used in this area? Or could you point me to a conversion table from AWG to metric.

I think you may have some problems due to the weight of the cable.
2/0 4C 649 lbs/1000ft 210 amps
3/0 4C 801 lbs/1000ft 240 amps
4/0 4C 991 lbs/1000ft 280 amps
336 4C 1591 lbs/1000ft 330 amps
If your load is 455 amps, you would require 2 - 3/0 cables.
What is the estimated distance for the installation?
