WebSep 15, 2016 · Sizing. VFD sizing should always be based on motor current and voltage, not hp. Let’s begin with the basics by learning how to read a motor nameplate. The nameplate in Figure 1 shows that motor current is based on the input voltage: volts (V) 230/460, full load amps (FLA) 13.4/6.7. WebAug 26, 2024 · And according to the NEC, a 5 HP motor has an FLA of 28 amps. So you need to assume your motor has an FLA of 28 amps, regardless of what the motor says. Second of all, the wiring needs to have an ampacity of 125% of the FLA. So, 28 x 1.25 = 35A. That means #8 Romex, or #10 THHN if you're running conduit. The breaker can be …
