Smart meter diatribe

I dare say that the software could do anything that EDF wanted. However, the RCD still needs to be there for basic protection; and if the smart meters were to be used for overload "protection" (of EDF's finances!) then either they would have to switch back on after an interval, or else they would have to have a reset button.

I agree the 500mA RCD would still haver to be there (for fault rather than basic protection) - but if the smart meter does the demand limiting then a simple conventional (i.e. cheaper) off the shelf unit could be used instead. As for reset, I'm not sure of EdF's policy. I understand that in Spain the similar arrangement requires a call-out to the supplier to snip seals to reset the MCB (presumably along with the payment of a fee) - deliberately to discourage abuse. EdF might do similar - in which case a phone call to the supplier (& possible penalty payment) and then the supplier could command re-connection remotely (or similar via a web page or smart phone app) - or if customers are free to reset, then presumably the existing buttons on the smart meter for navigating the various menus and registers could be used (a double press or long press at an appropriate stage perhaps) or even via a button on a suitable in home display.


Smart meter implementation of load limiting would possibly be much more flexible too - e.g. allowing a higher limit during say overnight off-peak times and a lower limit during peak times.
