Have a look at https://www.youtube.com/watch?v=L6ZXH2a_0Vs to see a Hagar AFDD not detecting an arc from about 4 mins in. The commentary is in French which I do not speak so it may be that their electricians are as skeptical about the effectiveness of AFDDs as many here.


In a report on electrical fires in America (https://www.nfpa.org/News-and-Research/Data-research-and-tools/Electrical/Electrical)

 it says 

• Arcing was the heat source in approximately three of five home fires involving an electrical failure or malfunction.

In another document it mentions arcing in nearly every cause of an overeating by damaged cables.


Given the implication that arcing is present in nearly every case of overheating the case for AFDDs is clear. This was used as the argument in another document, I cannot now find, for the introduction of AFDDs in USA. However I cannot find any figures saying how electrical fires have decreased since their introduction. If there are some figures they are not as easy to find as the claims made about the lives that will be saved by the introduction of AFDDs. 


I can see an increase work for Bodgit and Scarper. Who is going to pay for a new consumer unit incorporating AFDDs at over £1000  with all the paperwork when B&S will do it for a £600 without any paperwork or AFDDs.


Would an AFDD have stopped the tumble dryer fires or the fridges that caught fire, it is a genuine enquiry as I do not know.
