IMPORTANT, as under sizing the wire may lead to a phase converter that does not start or work properly. To minimize voltage drop, American Rotary recommends increasing wire size one size for every 50 feet of run and rounding up. -
Page 10: Wire Sizing Recommendation
2.1.4 WIRE SIZING RECOMMENDATIONS *For all voltages: Conductors recommended are based off minimum single phase breaker which is sized based on largest hard starting load & CNC amps. For combined HP’s greater than 50% of maximum total HP listed in the tables above, consult NEC & local codes for conductor sizing. -
