What are the efficiency standards under EISA?
For each general-purpose rating (Subtype I) from 1 to 200 hp that was previously covered by EPAct, the new law specifies a nominal full-load efficiency level based on NEMA Premium efficiency as stated in NEMA MG 1, Table 12-12. All motors now under EPAct, and manufactured after December 19, 2010, must meet or exceed this efficiency level.
