Answer / at

for 50KW motor
p=50
I = 50x 1.2 (thumb rule)
=60 A

Size of cable : 60x0.2(thumb rule)
: 12

so min size of cable req. 12 sqmm.

Answer / arpit patel

How 50kw motor current rating in 60 amp

Answer / manojkumar

BY SIMPLE
CURRENT DENSITY = LOAD CURRENT/AREA

FOR COPPER OR ALUMINIUM CURRENT DENSITY CAN BE VARIED ACCORDING TO OUR DESIGN.FOR GOOD DESIGN CURRENT DENSITY SHOULD BE REDUCED WHICH HELPS IN EASY TEMPERATURE DISSIPATION.

CONSIDER CURRENT DENSITY OF 0.6A/SQ.MM FOR cu OR AL
LOAD CURRENT-100A
THEN
0.6=100/AREA
AREA=166 SQ.MM

MEAN THAT 166 SQ.MM REQUIRED TO CONDUCT 100A.

Answer / karthik raman.b
