context_page_description: South African National Standard 164: Plugs and socket outlets for household and similar purposes for use in South Africa is the South African Bureau of Standards' standard for domestic AC power plugs and sockets. As a former British colony, South Africa's electricity standards are of British derivation, and it uses 220/230 V at 50 Hz AC.
  However, while the UK changed over to the rectangular-pin BS 1363 plug after World War II, South Africa has retained the older round-pin BS 546 style. This round-pin style was current in both the UK and South Africa when South Africa gained independence in 1931.
  Consequently, through much of the rest of the 20th century, both the smaller BS 546 5 ampere plug and socket, and the larger BS 546 15 ampere plug and socket, remained commonly in use in South Africa until the SANS 164-1 and SANS 164-2 standards were strictly defined in 1992. In 1994 these two new modern SANS 164 standards were implemented. Through the 1980s and into the 1990s the SANS 164-1/BS 546 15 ampere standard was largely in the process of replacing the smaller BS 546 5 ampere standard, and thus it became the most prominently utilised standard from 1994 on.

  South Africa has adopted the IEC 60906-1 plug and socket as SANS 164-2 in 1992. More recently however it has been selected by the South African Government as the "preferred standard" in 2013, and is being pushed to slowly replace the SANS 164-1/BS 546 15 ampere standard. Although the sockets are compatible with the Europlugs, which are already in common use as SANS 164-5, and Brazil has adopted a modified form of the same IEC 60906-1 standard, South Africa is the first country to adopt the IEC 60906-1 standard directly and implement it.
  The standard is divided into seven parts:
  SANS 164-0: General and Safety Requirements
  This incorporates IEC 60884 for definitions and general requirements. First implemented in 2006, it effectively replaces an earlier separate standard set by the South African Bureau of Standards (SABS for short) for plug and socket safety (SABS 1664).
  SANS 164-1: Conventional System, 16 A 250 V
  This is identical to the BS 546 15 ampere plug and socket, although in South Africa it is rated for 16 A for compatibility with the IEC 60898 standard current ratings. By 1992 the BS 546 15 ampere system had been codified by the SABS as SANS 164-1. This standard remains in effect today and it is the most commonly used plug and socket system currently in use in South Africa. However, after a transition period of 10 to 20 years, it is planned that SANS 164-2 will replace SANS 164-1 as the dominant standard.
  This plug-and-socket system is equivalent to the IEC "Plug Type M" system.
  SANS 164-2: Conventional System, 16 A 250 V
  This specifies the IEC 60906-1 plug system, both 2-pin unearthed and 3-pin earthed. Codified by the SABS as a South African standard since 1992, it was designated the "preferred standard" in 2013. Since 2015, South Africa has been in a planned transition period lasting 10 to 20 years (till either 2025 or 2035) to replace SANS 164-1 with SANS 164-2 as the dominant plug and socket system. The sockets are compatible with the SANS 164-5 Europlug which is also currently in common use in South Africa.
  This plug-and-socket system is equivalent to the IEC "Plug Type N" system.
  SANS 164-3: Conventional System, 6 A 250 V
  This is identical to the BS 546 5 ampere plug and socket, although it is rated for 6 A in South Africa for compatibility with the IEC 60898 standard current ratings. This standard was first codified by the SABS in 2006. Although the SABS standard was only defined in 2006, plugs and sockets of this form are normally only found in older installations of South African households, as both the BS 546 5 ampere (equivalent to SANS 164-3) and the BS 546 15 ampere (equivalent to SANS 164-1) were common in South Africa until 1992, when SANS 164-1 became the dominant standard for most household applications. Thus, plugs and sockets of the SANS 164-3/BS 546 5 ampere type are not commonly seen in households in South Africa anymore, having largely been
