Per NEMA is 2 bands -OR (as applicable) 2. Per EISAct 2007 law requires the motor losses to be no more than 15% lower than namplate. Referred to the federal registry 10 CFR Part 431, and section 431.24.

GE’s XSD Ultra ® family of products, offers ‘minimum guaranteed efficiency’ at 1 band below the nominal value. Comparison, of ‘1-band low’; for minimum guaranteed efficiency levels (Per NEMA).
