Thank you. I went ahead and actually bought SANS 556-2-1:2018 Ed 1.01. The SANS standard references IEC 60947-2:2016 with some amendments. Unfortunately it doesn’t reference IEC 61009-1 which seems to be the main standard for RCBOs internationally. So it’s not clear if compliance to IEC 61009-1 alone would make a RCBO compliant to SA standards.
Just to add, this is the specific RCBO model I want to install: https://www.se.com/uk/en/product/A9D...a-30-ma-240-v/. I was able to buy these for around 45GBP before shipping and import duties and VAT.
