The act will replace the current EPAct legislation which has been in force since 1997 and covers low voltage, "General Purpose" 3-phase electric motors from 1-200HP (0.75 - 150 kW). It will enforce a rise in the minimum efficiency of these machines from NEMA Energy Efficient to NEMA Premium Efficient. The new law will go further as it also encompasses motors not previously within the EPAct scope. The result is that almost all low voltage, 3-phase electrical induction motors will be covered by this new legislation. It can be summarised as follows: - 1-200 HP General Purpose motors currently covered by EPAct will change from NEMA Energy Efficient to NEMA Premium Efficient. - 1-200 HP motors not covered in point 1 above will comply with NEMA Energy Efficient. - 201-500 HP motors will comply with NEMA Energy Efficient.
