(10) Voltage drop should be considered when determining wire size.
Voltage drop can be calculated using the following equation:
Phase-to phase voltage drop (V)
= √3 wire resistance (Ω/km) × wiring distance (m) × current (A) × 10
-3
Select a wire size so that voltage drop will be less than 2% of the
normal rated voltage.
