So basically I can size the VFD from the motor nameplate info?
Size VFD to the motor name plate info AND the application. Watch out for the duty cycle table for instance. Two have stated VT/CT aka ND/HD ratings and there are special attention applications like compressors and crushers and rock quarry screens where even the VT/CT rule doesn’t work.
Size cables to motor size as per normal 430 procedure…normally 125% but again duty cycle matters.
On the feed side you use 125% of the VFD rating (in amps) as per 430 for wiring. The VFD is the load. Ignore the motor. OCPD as mentioned must follow manufacturers guidelines. Fortunately fewer of them are specifying exotic fuses these days.
