A 3PH MOTOR RUNNING IN NORMAL CONDITION AND ITS AMPERE ALSO
UNDER ITS FULL LOAD CURRENT,ITS CABLE RATINGS ALSO HIGER
THN ITS CAPACITY,BUT ITS CABLE GETTING ABNORMAL HEAT(NOT
TOO HOT)WHY ITS GETTING HOT LIK THIS?

Answer Posted / akm

lugs can heat the cable to only some mm near vicinity of
screwing so its not the case I think.
may be that insulation of cable becomming low or temrature
exposure of cable is high
