Sorry I don't know how to post up a youtube link but have a look at the John Ward one part 2 on AFDD's worth a watch.

Good point Mate, but with some of the prices of AFDDs being bandied about, I think the decision not to use them will be a financial choice.AFDDs are a response to an American problem, 30k housefires a year caused by high-current radials in wooden buildings, and what we would call substandard wiring - lots of wire nuts, for example.
A feature of RFCs is they don't arc if there's a single break, a safety factor that AFDD makers want us to abandon, just so the AFDD can detect an arc if a break happens. In other words, increase the chances of a dangerous fault just so an AFDD can detect it.
Sparks are supposed to recommend AFDDs and note if the customer declines. How is the customer meant to make that technical judgement?
A pretty damming example of how these AFDDs aren't all they are made out to be, it was a low load, but how much will it take to start a fire?????? good video JWSaw it earlier. Makes you wonder if they are any good?
Its the downside to letting commercial interests get on the jpel/64 and influence regs. The companies that make them have seen ÂŁ signs galore with these.
