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.
*

IMPORTANT
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) =
x wire resistance (
Ω/km) x wire length (m) x current (A) x 10
