Electrical code chapter 9 table 8. Referencing the NEC Chapter 9, Table 8 indicates that the cable size with a voltage drop of 0.438 ohm/km or less is 1/0 AWG (70 mm) cable with a resistance of 0.399 ohm/km. Calculating the voltage drop for the 1/0 AWG (70mm) cable results in:

CM = No. 1, 83,690 circular mils, Chapter 9, Table 8 . VD = 3.5 volts (3.5 volts/208 volts = 1.7%) Operating Voltage = 208 volts – 3.5 volts. Operating Voltage = 204.5 volts.
