In conclusion if you are installing sockets in a building that requires AFDDs don’t install RFCs.

Things can be in the regs even without a tester - after all there's never been a tester for the magnetic or thermal parts of an MCB/RCBO, only for the residual current part. Dame goes for fuses for that matter. so we have no idea if they still work when doing inspection and testing.
'premises with sleeping accommodation' is a bit ambiguous, though. I'm assuming they mean hotels?
Yes, you can just look at the switch or at the melted fuse. But the same applies to the afdd. I thought people meant testing the device itself for correct operation, which you can only do with rcds.But if a fuse blows or an MCB trips you have test equipment to diagnose the fault quickly and reliably every time.
Yep.It is very ambiguous. The Oxford Dictionary says 'Accommodation' is "A room, group of rooms, or building in which someone may live or stay. ‘they were living in temporary accommodation’ "
Doesn't that put every house down as having "sleeping accommodation" ?
With fuses and mcbs you can only test the circuit.
With afdds not sure! Maybe neither?
Yep.
Fortunately 421.1.7 has two softeners for now. It says "If used..." and then gives "Examples of where such devices can be used...". This will change to "shall be used" at some point I guess.
