Global Electrical Standards
NEC or IEC? Electrical Standards listed by country.
When you are working on a project that is in a foreign country it can be difficult to know which electrical standards are applied to the building code – the National Electrical Code (NEC) or the International Electrical Code (IEC). Most of the world, outside the U.S. and its neighbors, have adopted a version of the International Electrical Code. For example, all of the European Union countries use a version of the IEC, however, they have small differences and sometimes create whole new translations for their local languages. Some countries have created their own version of the International Electric and others have adopted editions from other nations. Needless to say, with multiple codes and multiple versions of electrical codes, it can be confusing which countries use exactly what code.
Here we have collected electrical code information for many of the countries of the world. We have tried our best to present this as complete and accurate as possible. If you have updated information we would appreciate it if you could please contact us via the form below with your suggested corrections.
