SA’s Schuko Plug Ban:
A Decade of Safety and Standards
In 2013, G. Campetti’s technical article described the banning of Schuko in South Africa. Over a decade later, the question remains whether this ban was an error.
Safehouse takes a closer look.
History of the Schuko System
The Schuko plug and socket system originated in Germany in 1926 and was adopted in many European countries. Attributed to Bavarian manufacturer Albert Büttner, whose company obtained a patent for a ‘plug with earthing device’ in 1930.
South Africa’s Ban and Legal Amendments
South Africa banned the sale and use of the Schuko configuration in 1999, for both technical and safety reasons. An amendment to the Compulsory Specification (Government Gazette No. R 858, 9 July 1999). Added clause 3.3 to VC8008 1998. Banning earthed Schuko plugs but not sockets.
The South African Wiring Code (SANS 10142-1) initially listed Schuko sockets as acceptable for fixed electrical installations under the Compulsory Specifications. In 2010, Government Gazette No. R 1075 introduced an amendment through the National Regulator for Compulsory Specifications Act (Act 5 of 2008).
This update provided clearer guidance on plug and socket regulations. To improve safety, compliance, and consistency across all electrical installations in South Africa.
SA Standard Configurations for Plugs and Socket Outlets
In 2006, due to objections from the Power Tools Consumer Safety Association (PTCSA), an addition was made to the SA Standard Configurations. SANS 164-6 described an unearthed Schuko-type plug and socket designed for double-insulated tools and appliances.
Creating a compromise allowing unearthed Schuko plugs and sockets. However, the NRCS retained the authority. To issue directives against the sale of earthed Schuko devices and to deny COC certification for installations including them.
The NRCS Act and the introduction of LOAs.
The introduction of the NRCS Act in 2008 brought about changes to compulsory specifications. And the Letter of Authority (LOA) process was impacted. Industry stakeholders submitted objections to VC8008 updates, aimed at ensuring product compliance and safety oversight.
Motivation Behind the Schuko Configuration Ban
The externally accessible sliding-earth mechanism could compromise earth leakage protection, as it was easily damaged. A 2010 amendment under Government Gazette R1075 led to the 2011 formal ban on earthed Schuko plugs and sockets.
Conclusion
In Conclusion, the Regulator (NRCS) is entitled to issue a directive to any distributor to withhold sale of any earthed Schuko plug, socket or adapter. No registered electrical contractor may issue a Coc for any installation that includes earthed Schuko socket outlets.
