a Premium efficiency electric motors usually have higher inrush current than equivalent models. In older buildings, make sure existing circuits and protection equipment are adequate to handle this higher initial current, especially when replacing "Design B" with "Design A" motors.
b This requirement applies to general-purpose, single speed, polyphase induction motors. Some applications require definite-purpose, special-purpose, special frame, or special mounted polyphase induction motors. A motor meeting this efficiency requirement should be available for these other applications.
c Motor efficiency is identified on the nameplate by "nominal" efficiency, which represents the average efficiency of a large population of the same design. It is measured in accordance with NEMA MG 1-1998, Motors and Generators, and IEEE 112 Test Method B.
