The imminent rise of the AFDD in UK wiring regulations

Arc Fault Detection Device The AFCI technology using a different acronym AFDD, is on the horizon for implementation in the UK and many people are afraid.  Is this true and should we be afraid of change?

Some years ago I wrote a post on why the UK didn't use AFCIs while they are commonly used in North America.  In fact AFCIs are mandatory in the US and Canada to protect certain final circuits in the same way that RCDs, in the form of RCCB and RCBOs, are mandatory in the UK for most final circuits.  There has been a lot of grumbling over the pond about this technology but what does it mean for the UK.
