670.3 Machine Nameplate Data
670.3 Machine Nameplate Data
(OP)
This section of the NEC tells how to calculate full load amps of multi-motor equipment. I understand how this works, I know when to use the FLA tables for wire sizing etc. My question: When listing the FLA on a piece of equipment and/or wiring diagram, do you use the actual motor nameplate or the FLA tables? I am often asked the full load amps of our equipment, and I'm not sure whether I should answer with theoretical (FLA tables) or actual (calculated from motor nameplates). Thanks!

Use motor nameplate FLA.
List minimum circuit ampacity from calculations.
