Yes, you would use 430.52 to size the OCPD and 430 Part II for sizing the conductors for this application.

OCPD Sizing (430.52)

The full-load amperes (FLA) of the machine is 60A. 430.52 requires sizing the OCPD at 125% of the FLA rating. Therefore, the OCPD size is: 60A 1.25 = 75A.

Conductor Sizing (430 Part II)

Part II of Article 430 provides tables for sizing conductors for motors. For a 3-phase motor operating at 208V, the table in 430.250 indicates the following minimum conductor sizes: Phase conductors: 4 AWG copper Neutral conductor (if required): 1/0 AWG copper

Note: You may also need to consider other factors such as ambient temperature, wire type, and conduit fill when selecting the conductor size. It is recommended to consult with a qualified electrician or electrical engineer to ensure proper sizing and installation of the electrical system for this machine. Flag for review
