There have been debates about this on the IET site since the 18th
came
in. The opinion is that RCD fused spares are now not allowed,on their
own, as BS7288 says they need additional protection before the device.
In real life terms, a fused spur would be fine, but the Committee doesnt
seem to think it is enough, but havent explained their reasoning.
I've not looked into it recently, 2 links here from last year going into
more detail.
