Editing Residual-current device (section)

=== South Africa ===
South Africa mandated the use of Earth Leakage Protection devices in residential environments (e.g. houses, flats, hotels, etc.) from October 1974, with regulations being refined in 1975 and 1976.<ref>[http://www.ee.co.za/article/the-importance-of-installing-earth-leakage-units.html The Importance of Installing Earth Leakage Units]</ref>
Devices need to be installed in new premises and when repairs are carried out. Protection is required for power outlets and lighting, with the exception of emergency lighting that should not be interrupted. The standard device used in South Africa is indeed a hybrid of ELPD and RCCB.<ref>{{cite book|title=SANS 10142-1|date=2009|publisher=SABS Standards Division|isbn=978-0-626-23226-9}}</ref>
