as time moves on and opinions shift - especially via pressure from changes in Regs, H&S, CP Scheme influencers; what was once safe is now not safe and all that !
e.g some now may consider the lack of RCD additional protection to skts (even if everything else is ok) is a potentially dangerous situation, where as previously that may not have been the case; same goes for lack of RCD to lighting circuits and even more so if circuit serve/pass a bathroom .
therefore, to the subject question as written ... what's the consideration 'today' please ?
and then, same question but where RCD protection on the RFC is present ?
and best wishes to all for a lovely day
