Organization: IEEE
Publication Date: 24 June 2004
Status: active
Page Count: 25
scope:

This recommended practice is limited to auxiliary devices associated with rotating electrical machines operating in Division 2 or Zone 2 areas, classified as Class I under the practice of NFPA 70-2005, National Electrical Code® (NEC®),1,2 CSA C22.1-02,3 or Zone 2 areas classified under the practice of IEC 60079- 10-20024 and CENELEC EN 60079-10-1996.5 This recommended practice is not an attempt to rewrite or otherwise supersede applicable sections or clauses of these noted documents or any other codes or ordinances. Rather, it is intended to serve as a supplement to existing codes that in this area may not be sufficiently specific to serve as a guide to good engineering practice.

Purpose

The following information is intended to bring together a brief description of basic electrical practices with regard to the application and installation of auxiliary devices to rotating electrical machines operating in Class I, Division 2 or Zone 2 locations using NFPA 70-2005, National Electrical Code, CSA C22.1-02, or Zone 2 locations using IEC 60079-14-2002 and CENELEC EN 60079-14-1997. It should be understood that this information is only a recommended practice to promote consistent application of such devices and must be used with sound engineering judgment.
