Note :
(1) Dol - Single Cable 1 HP - 7.5 HP Star - Delta - Double Cable 10 HP and above.
(2) For Star Delta Starting reduce current by 1/3 for selecting suitable cable
Example :
For a 20 HP motor at 350 volts & 90 meters actual cable length, calculated lenght = (415 / 350) X 90 = 107m.
The size of the cable to be selected for 107m, from the cart is 6 mm2
Converstion Table : 1m = 3.28ft & 1ft =0.305m
For other Voltages the cable size is to be selected as Follows : Calculated length : (220/Volt)xactual length
