AFDD performance standards, installation for a timber framed new build

Sizzles
Hi,


I'm building a house based on a SIPS timber frame, and I'm going through the process of designing the wiring.  I'll be installing the electrics myself and have someone to certify the work.


I have been considering the electrical design for the building and looking at AFDD as a means of providing additional protection. Watching some of the testing videos done by John Ward on YouTube I note that different devices from manufacturers seem to behave very inconsistently. 


Given the large investment (~ £150 per device) I'd be interested to hear the forums opinions on the quality standards in force. I was quite happy to invest in these devices at first, but I'm not convinced that the quality between manufacturers is nearly good enough.

    Thanks for the input.  Some interesting ideas for me to consider. 


    I have indeed found an electrician to work with me.  It turns out the the local building regulations people are obliged to provide a service to DIY'ers like myself, in this case it is outsourced to a local company who do 3 inspections and a formal test.


    I had a lot of trouble from the local "closed shop" electricians who all refused. Never mind the fact that I am a Chartered Electrical Engineer with years of experience. I asked one guy if he knew what "Lenz's Law" was, he went off in a hump....
