Table 44 of CEC 2006 Part I and the NEC Motor FLA Table are similar and they indicate Full Load Amps for various HP and voltage ratings. Note 4 of these tables indicates that for 90% and 80% power factor, 1.1 and 1.25 are to be multiplied to the FLA values in the tables. My question is, at what %PF BASE or %EFFICIENCY BASE are the values on the table derived from. I am trying to create a typical motor FLA database and hoping to derive them from Code tables as part of my conductor sizing calculations...Any comments?
I would appreciate if somebody could share me a typical FLA table for various voltages which I can conservatively use aside from the Code tables as an option. Thanks
