| IEEE | 2023 |
Revision Standard – Active. This recommended practice applies to the application and installation procedures of auxiliary devices in or on electric rotating machines that are employed in hazardous locations classified as Class I, Division 2 and Zone 2 and Class II, Division 2 and Zone 22 under commonly used worldwide regulations. These regulations are: the National Electrical Code® (NEC®); the Canadian Electrical Code (CE Code); and combined practices of the International Electrotechnical Commission (IEC). Included is a list of source documents, definitions and nomenclature. Devices include terminal housings, heaters, surge protection, power factor correction capacitors, shaft bonding (shaft grounding), and enclosures. Special marking requirements are also discussed.
