Motor Compliance Certification (CC) Numbers The Department of Energy (DOE) has mandated energy efficiency levels for certain classes of 1- and 3-phase electric motors. For certain categories within these groups of energy efficient motors, a Compliance Certification (CC) number that is unique to a specific motor manufacturer, assigned by the DOE, must appear on the motor's nameplate. The CC number is listed in the Tech Spec section on Grainger.ca for affected motors.

Hazardous Location Motor Temperature Codes In addition to identifying the Class, Group, and Division of the hazardous location motor, you must also obtain the temperature code or maximum surface temperature for the motor. This code or temperature indicates the maximum surface temperature for all conditions including burnout, over- load, single phasing, and locked rotor. The maximum surface temperature or T-Code must be identified on the nameplate.

TEMPERATURE IDENTIFICATION NUMBERS “T” Number Max. Temp. “T” Number Max. Temp. (T-Code On Nameplate) (For All Conditions)

(T-Code On Nameplate) (For All Conditions) T1 450ºC 842ºF T3A 180ºC 356ºF T2 300ºC 572ºF T3B 165ºC 329ºF T2A 280ºC 536ºF T3C 160ºC 320ºF T2B 260ºC 500ºF T4 135ºC 275ºF T2C 230ºC 446ºF T4A 120ºC 248ºF T2D 215ºC 419ºF T5 100ºC 212ºF T3 200ºC 392ºF T6 85ºC 185ºF

National Electrical Code Explosive Atmosphere Classifications Certain locations are hazardous because the atmosphere may contain gas, vapor, or dust in explosive quantities. The National Electrical Code (NEC) divides these locations into Classes and Groups according to the type of explosive agent which may be present. Listed are some of the agents in each classification. For a complete list, see NFPA (National Fire Protection Association) publication 497M. Underwriters Laboratories tests motors and other devices for safety in explosive atmospheres, and publishes a list of those products that meet its standards for each Class and Group. Use of UL Listed devices does not necessarily make an installation conform to the NEC or local codes. Consult Chapter 5 of the NEC, local building codes, OSHA requirements, and insurance inspectors for detailed data as to proper procedures. This catalog does not contain any motors designed for Class I, Groups A or B atmospheres.
