The £1300 AFDD consumer unit

It is quite good, but contains all the things we have discussed, and it seems that this man thinks they will cost the same as an RCBO soon! He has measured the electrical consumption and they cost an additional £8.34 for the electronics power, on economy 7. So call that £13.00 for those without, or a waste of £400 million a year if we all have them. About the same as two LED lamps on all the time in every home in the land, and they want us to reduce electricity consumption, really joined-up thinking!

Shower and EV charger supplied from a secondary consumer unit, so sharing a 40 amp AFDD in the main CU?

And all on a 60 amp supply?

I think the 'Deviations' column is going to get some hammer in the forthcoming years. Personally, I cannot see a use for these devices other than to enhance the manufacturers bottom lines.

I hope there’s some load shedding.

If you watch the video he explains that both circuits are on one of those GARO change over load shedding cu/switch.s

If AFDD are going to be fitted I can foresee no more than half a dozen circuits in a consumer unit.


Lighting, sockets, cooking appliances, heating and EV charging. If the heating is on a 40 amp circuit that would be five AFDD.

This man has too much time on is hands at home. The arguments used reached the Reductio Ad Absurdum position. I will stick with my 4 way 1970s Wylex fuse box. I have had no trouble with it and it costs nothing to run at all.

I have a lot of time for Mr Savery and his schoolboy humour - a moment of sanity in a ever maddening world.I do fear however, that he has been got at in the same way that other respected pundits and sceptical commentators have been since the inception of SPDs, AFDDs etc.


Just as an aside - SPDs. My guess is that a significant number of these devices have been installed during the last couple of years. How many I wonder, have had to be replaced because they have been activated one time too many? I wonder what the sales figures for replacement SPD untis is right now - or perhaps, as we suspected all along, there wasn't a real 'surge' problem to begin with?
