Model vs. Rule

  • The efficiency value for a given model will not change.
  • The efficiency level is what it is.
  • ONLY the rules for using a particular motor will change.

EPACT efficiency levels/values are the same now as they will be in 2010 - NEMA MG1 Table 12-11(see note below).

NEMA Premium efficiency levels/values are the same now as they will be in 2010 - NEMA MG1 Table 12-12 (see note below).

How to check a Model for Compliance/Changes

1. Check the model details to see what features it has. What makes the motor NOT general purpose? Voltage, frequency, feet, vertical mounting, etc.

2. Look at the rules below. Are any of those features still considered special? If not, the motor must meet EPACT or NEMA Premium.
