WE HAVE A LOAD OF 55KW MOTOR ITS VOLTS 380 3PH AND ITS
TAKING 100AMPS (ITS FULL LOAD IS 105AMPS)AND ITS CABLE IS
4CX50SQMM ,NOW ITS GETTING ABNORMAL HEATUP IN CABLE,PLZ
TELL WHY ITS HEAT-UP?(CABLE LENGTH IS 15 METERS ONLY)

Answer Posted / laxmi

if you are used 50sq.mm alu.cable it may not sufficient to
carry the 100 amps current,for alu. cable 1A for 1Sq.mm is
a safe factor load.if your cable is copper it is enough to
carry your load.as per your information your cable length
is not a problem.
