The £1300 AFDD consumer unit

Stewart Ross:

An interesting video. I had not appreciated that AFDDs available at present use dedicated microprocessors. I have my doubts about incorporating complex technology into a consumer unit whose lifespan should be much, much longer than the typical consumer goods cycle that leads to new releases currently every 18-24 months for phones etc. Will these devices be reliable enough in practice? If they aren't, will they be directly replaceable on failure or will the latest 'update' force a wholesale replacement of all other devices (as David Savery found he had to do as the bus bar connections on the new AFDDs were not compatible with the other devices in his DB).


Despite his ribald humour, David Savery has put out an interesting series of videos and at least is doing something to advance the discussion. I commend what he has done to move the debate forward.


Anyways, I remain unconvinced that there is any need for AFDDs at all, but that's a view I've already made in a response to the DPC.

I agree with the posting above. I was amazed at the complicated internal construction of an AFDD and wondered what the electrical strength/resistance to surges was. I wasn't successful in tracking down the surge withstand strength information on the internet. It would be ironic if the introduction of AFDDs required the addition of SPDs!
