Cable Capacity
The cable capacity shall be determined according to the motor rated current with the supply voltage
fluctuation and voltage drop. Please consult with the person in charge of electricity or electric spe-
cialists.
[ 1 ] Supply voltage fluctuation and line voltage drop
(1) The voltage received by the loom drops due to supply voltage fluctuation and the voltage drop at delta-
starting by the cable resistance. Keep the total voltage drop within 10% of the contract voltage.
