For 400V 3ph AC system
# For 1% permissible voltage drop
size of cable in mmsq (aluminium cable)=( I*L) /80
# For 2% permissible voltage drop
size of cable in mmsq (aluminium cable)=( I*L) /160
# For 3% permissible voltage drop
size of cable in mmsq (aluminium cable)=( I*L) /240
I = Full load current
L = Length in meter from load center to motor
