Answer Posted / reddy
cable size can be selected like ,suppose if u have any
motor with u of 110kw and its full load current is 190 then
when it is in dol stater starting torque is high up to 2
times of that full load so we have to use 300sq mm.if it is
in star delta 240 sq mm is enough because in a star
starting current is low it means 70 to 60 percent of full
load .after that some time delay delta pick ups
