Abstract :
The authors discuss the role of motor internal, as well as external, surface temperature in determining if totally enclosed motors are safe for use in Class 1, Division 2 locations. The implications of using adjustable speed drives with TE motors are discussed. Recommendations are proposed for changes to the National Electrical Code (NEC), user application criteria, and additional nameplate information to be provided by the motor manufacturer
