General purpose electric motor (subtype I)

means a general purpose electric motor that:

(1) is a single‐speed, induction motor;

(2) is rated for continuous duty (NEMA MG1 – 2009) operation or for duty type S1 (IEC);

(3) contains a squirrel‐cage (NEMA MG1 – 2009) or cage (IEC) rotor;

(4) has foot‐mounting that may include foot‐mounting with flanges or detachable feet;

(5) is built in accordance with NEMA T‐frame dimensions or their IEC metric equivalents, including a frame size that is between two consecutive NEMA frame sizes or their IEC metric equivalents;

(6) has performance in accordance with NEMA Design A (NEMA MG1 – 2009) or NEMA Design B (NEMA MG1 – 2009) characteristics or equivalent designs such as IEC Design N (IEC);

(7) operates on polyphase alternating current 60‐hertz sinusoidal power, and:

(A) is rated at 230 or 460 volts (or both) including motors rated at multiple voltages that include 230 or 460 volts (or both), or
