ELECTRICAL INSTALLATIONS OF BUILDINGS : RESTRUCTURING OF IEC 60364



With the publication of 10 new standards, the International Electrotechnical Commission has now restructured its IEC 60364 series, an essential tool for designers and constructors / installers of electrical installations. The restructuring affects the format and sequence of publications, without introducing any technical changes to their content.

Pelta Reinhard (Siemens AG, Erlangen, Germany), Secretary of IEC Technical Committee 64 (Electrical installations and protection against electric shock) explains that "the objective of the restructuring was to remove the fragmentation that had developed over the years in the preparation of the standard, no part of which stands on its own. By reducing the previously large number of single publications composing this complex standard and merging parts and clauses that logically belong together, the standard has now been made more user-friendly and understandable."

Reinhard adds that "IEC 60364 is the only international standard that covers the wide field of electrical installations of buildings. It applies to all installations, from those of lower complexity, such as individual dwellings, to extended and complex installations in industrial and commercial premises, such as factories or large office buildings. It covers all aspects of safety, including protection against electric shock and thermal effects. Essential functional requirements, such as electromagnetic compatibility, are also covered.
