Sorry i dont have the xat formula for that but

for ALUMINIUM CABLE: 1sq.mm = 1.2 A of current

CU: 1sq.mm = 5.0 A of current

and the relation b/w A & KW IS

1KW= 1000*A*240*COS#

A- CURRENT

240= VOLTAGE

COS# = POWER FACTOR (.8 TO .99)

NOW IF U KNOW THE EXACT CURRENT LOAD OR LOAD IN THE FORM OF

KW U CAN EASILY FIND THE AMPERE RATING. ...more
