*1 Wire size range provided for Drives using insulated screw-type terminal blocks. All other models require the use of UL listed connectors. Refer to Table 2.3.
*2 Recommended wire sizes are based on the normal duty (ND) current ratings and NEC Article 310 Table 310.16, 75 Degree Celsius copper or
equivalent. When sizing wiring based on the heavy duty (HD) current ratings, consult NEC Article 430 and any other applicable codes.
