* The wire thickness is set for copper wires at 75°C.
1
* Wire size range provided for Drives using insulated screw-type terminal blocks with a single conductor. Refer to applicable codes for proper wire type and size.
2
* Recommended wire sizes are based on the Drive current ratings and NEC Article 310 Table 310.16, 75 Degree Celsius copper or equivalent.
3
* Uses non-insulated screw-type terminals. Refer to applicable codes for proper wire type and size.

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:
Line voltage drop (V) = 3 x wire resistance (Ω/km) x wire length (m) x current (A) x 10
