Answer Posted / k.l.lim
ex 10kw 3 phase ac motor,
10kw x 1.74 = 17.4 amp
MCB using 25 amp/30 amp 3 pole(C)
Motor using star-delta/overload setting 0.58 = 10.1 amp
cable size = 6x2.5mm2/1c pvc copper cable
if using soft starter
MCB using 25amp/30amp 3 pole MCB(C)
cable size = 3x4mm2/1c pvc copper cable
cable size :calculate include starter overload setting
(right or wrong,thank's)L
