Guide for
Application of Electric Motors in Class I, Division 2 and Class I, Zone 2 Hazardous (Classified) Locations

 

Scope & Schedule

IEEE Std. P1349 Scope:  Three-phase and single-phase AC synchronous and induction electric motors in fractional ratings 0.18 kW (1/4 hp) and larger are covered in this Guide. Primary emphasis is on the use of open or nonexplosionproof or nonflameproof enclosed motors in Class I, Division 2 and Class I, Zone 2 locations as covered in NFPA 70-2005. Precautions against excessive surface temperatures and sparking of rotor bars and enclosure joints are also covered. This document also provides guidance for maintaining the life-cycle integrity of motors in Class I, Division 2 and Class I, Zone 2 locations as covered in NFPA 70-2005. This Guide does not cover AC wound rotor motors and DC electric motors. Motors installed in locations other than Class I, Division 2 and Class I, Zone 2 as covered in NFPA 70-2005 are not covered in this Guide. This document is not a specification and is not intended to be used as a specification for purchasing motors. The voltage breaks in this document are 1000 V and less, and over 1000 V.

IEEE Std. P1349 Purpose:   Existing codes and standards contain cautionary notes for open or nonexplosionproof or nonflameproof enclosed motors in Class I, Division 2 and Class I, Zone 2 locations as covered in NFPA 70-2005. This Guide documents industry experience and established practices and provides guidance for applying motors in these locations.
