IEC 60906-1 (Brazilian NBR 14136) (Type N)

A Brazilian socket for 20 A/250 V, meant for use with larger pins than 10 A version

In 1986, the International Electrotechnical Commission published IEC 60906-1, the specification for a plug that looks similar but is not identical to the Swiss plug. This plug was intended to one day become the common standard for all of Europe and other regions with 230 V mains, but the effort to adopt it as a European Union standard was put on hold in the mid-1990s.

Brazil, which had been using mostly Class II Europlugs (while households also commonly presenting socket fittings for the NEMA 1–15 and NEMA 5–15 standards), adopted a modified version of IEC 60906-1 as the national standard in 1998 (revised in 2002) under specification NBR 14136.There are two types of sockets and plugs in NBR 14136: one for 10 A, with a 4 mm pin diameter, and another for 20 A, with a 4.8 mm pin diameter, the latter used for heavier appliances such as microwave ovens. NBR 14136 was not enforced or encouraged in that country until 2007, when its adoption was made optional for manufacturers, becoming compulsory on January 1st 2010. It helped domestic consumers that most of Class II plugs fitted in the new IEC NBR 14136 sockets.

South Africa has also introduced the IEC 60906-1 standard as SANS 164-2.
