Global hazardous area requirements

This article highlights those improvements and serves as a short tutorial into current international codes for the implementation of sometimes hazardous electrical components. It focuses on North American engineers working on non-U.S. projects. Included is a general subject overview and in particular, a discussion of similarities and differences between the codes. IEEE recommended the practice of 303 auxiliary devices for rotating electrical machines in Class I, Division 2 and Zone 2 locations. It is now expanded to include the Canadian Electrical Code (CEC), International Electrotechnical Commission (IEC), European Committee for Electrotechnical Standardization (CENELEC), and Standards Australia/New Zealand (AN/NZS) regulations
