There seems to be a standard installation developing for domestic EV charge points where it is 6mm2 no matter what. I checked one installation which will have around 9v dropped on a 7Kw charger. Ok, I acknowledge that the full load current won’t be pulled at all times but it can be assumed that there will be long periods when it will. Multiply that by an ever increasing demand across the nation and we can expect to see considerable energy wastage. Perhaps, we should be setting tighter limits than 5%.
In my view, 3 phase should become the norm for most new domestic services.
I couldn't agree more, at least for properties bigger than a certain size. The newest development hereabouts allows 25 m² per adult.
However, I couldn't quite see a TPN board in most entrance halls. And a lot of sparks seem to be afraid of it.
And customers don't seem keen. Daughter is going to have an annex and garage built including EVCP and swimming pool heat pump, but so far I have failed to get any sort of engagement about the wiring. I guess if the architect said that she needed it, that would be fine, but his plans have already sliced through all the cables to the kitchen, etc. and the main bonding!
