To get accurate size give voltage, length, application and method of laying.
However 3 r X 300 Sq mm is ok.

Generation of voltage for each phase are same of a turbogenerator.Although the short circuit current flow when two phase of turbogenerator are shorted(where current can't flow without potential difference),why?
