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 made it as complete and accurate as possible but it may inevitably have some small errors. If you have updated information we would appreciate it if you contact us via email with your corrections. This way we can keep this information updated as a general reference of the electrical standards and codes throughout the world.

We are currently updating our “Electrical Code Information” to the most recent data. Please check back again soon.
