„ Closed-loop Connector Sizes
Determine the wire size for the main circuit so that line voltage drop is within 2 % of the rated voltage.
Line voltage drop is calculated as follows:
(If there is a possibility of excessive voltage drop, use a larger wire suitable to the required length.)
Line voltage drop (V) = 3 × wire resistance (Ω/km) × wire length (m) × current (A) × 10 -3
