Also I am still making alterations and additions to electrical circuits protected by BS4293 RCDs, but they are no longer listed in the current Wiring Regulations, so is that wrong, is there an issue about using these to provide RCD protection? If there is an issue millions of consumer units with working and safe RCDs that need replacing to undertake minor alterations and additions to existing electrical installations.
I'd say that there's no more of an issue than re-using red & black cables (which won't conform to the current version of BS 6004), BS 3871 MCBs or BS 1361 fuses. If anything a properly functioning BS 4293 RCD might even give better protection than a modern BS EN one - being that they'll disconnect within 200ms instead of 300ms (at 1x).
