Table 2.3 Closed-Loop Connector Sizes (JIS C2805) (200 V class and 400 V class) Determine the wire gauge for the main circuit so that line voltage drop is within 2% of the rated voltage. Line voltage drop is calculated as follows:
Line voltage drop (V) = Ч wire resistance (W/km) Ч wire length (m) Ч current (A) Ч 10 -3 3 2- 7 Wire Thickness (mm2) Terminal Screws Size 0.5 M3.5 1.25 to 3.5 M4 1.25 to 4 0.75 M3.5 1.25 to 3.5 M4 1.25 to 4 1.25 M3.5 1.25 to 3.5 M4 1.25 to 4 2 M3.5 2 to 3.5 M4 2 to 4 M5 2 to 5 M6 2 to 6 M8 2 to 8 3.5/5.5 M4 5.5 to 4 M5 5.5 to 5 M6 5.5 to 6 M8 5.5 to 8 8 M5 8 to 5 M6 8 to 6 M8 8 to 8 14 M6 14 to 6 M8 14 to 8 22 M6 22 to 6 M8 22 to 8 30/38 M8 38 to 8 50/60 M8 60 to 8 M10 60 to 10 80 M10 80 to 10 100 100 to 10 100 M12 100 to 12 150 150 to 12 200 200 to 12 325 M12 x 2 325 to 12 M16 325 to 16 IMPORTANT
