It’s a boo from me, I’m afraid! Despite deep dive research, I can find no statistical evidence that would support a positive outcome of a cost benefit analysis. I have been a member of the IPFO for as long as I have been MIET. I have paid particular attention to fires with fatalities, especially in the hospitality sector, and I have read many forensic reports. I can find none where an AFDD installed as currently prescribed in 7671 would have led to a different outcome. To be fair, data is pretty weak whether you are for or against the things but thrusting these devices on the electrical installation industry should have come with reference to a robust evidence base.
