I recently received a motor with nameplate in two parts.
Part 1:
Interter data
20 HP
6-60 HZ
460 V
23.6 Amps
1.0 service factor
Part 2
Sine Data
25 HP
60 HZ
460 Hz
29.7 Amps
1.15 service factor
The motor will be installed using a standard combination started (60 Hz) not a VFD.
Question 1 - Should the conduit, wire, starter, fuses, etc. be sized for per the NEC based on the 25 HP motor?
Question 2 - Is it a code requirements that if a drive is being installed on a piece of equipment with a standard motor (motor not rated by inverter service) that motor be replaced with a motor that is rated for inverter service?
