Answer Posted / mahendran
1 kw = 2 amps ie 148*2=296 amps
240 sq mm will carry 220 amps you make 2 * 240 =480 amps
this is actual amps for safety we give 755 load to the cable so
240*75%=380amps
150sqmmwilltake 180amps ie 2*180=360amps75%load
360*75%=270amps its less then your load
so you can select 2*240 sqmm cables
