Answer Posted / santosh
Sqmm of cable depends upon the cable material.In thumb rule Cu cable can carry 10-12 times of its rated sqmm.For ex 10 sqmm cu cable carry 100-120 amps.Al cable carry 4 times current of its rated sqmm
For ur problem: 13A is rated current. 50-60 amp staring current,7-8 running cu.So u may need 4 sqmm Al cable or 2.5 sqmm cu cable.

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
