IEC 60364 Table 48A

gkenyon:

And finally, we've openly permitted RCDs to deal with disconnection time not only in the UK, but also in CENELEC countries, and across IEC, for many years - at least 13 years now in the UK with current wording, but even further back in time being realistic, as there was a sort of "permissive" approach towards RCDs for automatic disconnection towards the later 16th Edition of the Wiring Regulations (BS 7671:2001 and perhaps earlier).


Is there any evidence that modern RCDs are failing to provide the protective function?

Maybe I'm wrong, but I read somewhere that RCDs can not be used to achieve disconnection in a TN supply where high EFLI is present. Could be wrong here.
