Pump Motor Efficiency: Is a trash compactor pump motor subject to the ENERGY STAR MFHR prerequisite for NEMA Premium Efficiency? Follow

No. While the prerequisite states that “All three-phase pump motors 1 horse-power or larger shall meet or exceed efficiency standards for NEMA Premium™ motors, where available,” it was not intended to apply to pumps in the building that have minimal operating hours.


Footnote 27 exempted motors for fire pumps and booster pumps for this reason. This exemption can be extended to trash compactor pumps as well.
