That's another diversity issue, and as you say, one that's rather
suspect.

However, given that the street wiring in much of the country is sized
for 2kW per premises, and they don't burn out very often, we can
conclude just from that evidence, that substation-premises diversity
does in fact work.

Just like the 15kW diversity in my house works (I haven't blown a main
fuse, ever) but if I added even an entry level 7.4kW EV wallbox I think
it probably would [blow the fuse]. I'm investigating getting it upgraded
to 100A as a result.

You can find effectively terraced houses each with off street parking.
Meaning it would make no difference to charge one car per house off or on

The subject of total capacity either local or national is a different

It makes a huge difference because the on-street charging points are
leeching off the 2kW/premises average for the housing.

Not very many on-street chargers would melt the cabling.

No, that's the mistake you are making, it applies to a large number
of residential premises (as an average).

Don't believe it's a low as that.

It is.

Don't believe it.

Not only is it true,

It might have been true when most cooked with gas,
but that hasn't been the case for a long time now.

but it's been mentioned by the National Grid as one of the main
constraints on the rollout of electric cars.

By some fool that doesn't have a clue.

They've got all the data.

Mindful also that 1kWh costs an average of 16p in the UK, which if we
multiply up as 18hrs x 365 days, would be a thousand pounds, and very
few people have electricity bills that big.

Irrelevant to what the load is when cooking the evening dinner.

Not everyone is cooking their dinner at the same time

It doesn't vary that much. In spades with xmas dinner.

(or are even at home). Quite a lot will also be cooking with gas.

Not enough to matter anymore.

There's probably more cooking with gas now than there ever was.

Not as a percentage of the houses in the street there isnt.

And plenty use electric fan heaters and radiators too.

Very expensive compared to gas.

Still happens and plenty don't have gas available.

And once again, not on simultaneously in every house in the street.

Doesn't need to be to **** the stupid 2kw per house.

6am to 10pm (14hrs), and then the second [remember, a car doubles the
average consumption] from 10pm to 6am (10hrs), which means the amperage
overnight is about one and a half that of the daytime. So the cable

It's a Tragedy of the Commons. In the short term I could be an early
adopter and have a charger installed, and my one extra load wouldn't be
especially significant. But as soon as several neighbours do the same,
the power company might have to start rationing new installations (or in
the longer term digging up the road to install a bigger cable).

In practice, what seems to happen first isn't actual cables melting
(that's a metaphor) or fuses blowing at the substation, but buried
junction boxes start going intermittent. There's a road near me where
they've dug up and replaced them piecemeal (every hundred yards or so)
over the last few years. So you get a good look every time they dig.

I think the extra demand in that instance has been new-builds/
extensions, rather than car chargers.

The fallacy is that because there's a street light (consuming 50 watts)
it should be possible to install a 7.4kW car charger to every one.

Or in fact several to each one, because on-street parking bays are
typically 8-10 per streetlight.

FFS. I merely pointed out you don't need a driveway to charge your car if
street points were provided. Any problems with the distribution system
apply equally to driveway charges and street chargers, like for like.

But carry on answering the question you hoped was asked.

peak period, and also when they tend to plug their cars in) it still
doesn't work, because you'd have one set of kWH-per-household from say 6am
to 10pm (14hrs), and then the second [remember, a car doubles the average
consumption] from 10pm to 6am (10hrs), which means the amperage overnight
is about one and a half that of the daytime. So the cable still melts.

Speed, the auto-contradicting senile sociopath, blabbered, again:

FLUSH the trolling senile asshole's latest troll**** unread

02:04??? And you've been up and trolling since 01:34 already, yet again! Are
your senile hormones not letting you sleep in again, you abnormal
86-year-old trolling senile pest?

But surely the local suppliers will think of that, and not let him if

You have to apply to the DNO for permission to install a 7kW charger.

Northern Powergrid sent out Freedom Network Services to check our
cut-out before they agreed to let us go ahead.

80A was installed and acceptable, 100A was more than required and they
were reluctant to upgrade to that.

I'm not sure what the diversity is at my house, but
earlier today my natural gas heating device quit (air inducer)
and the part won't be here until Monday. And I'm heating on
approximately 9kW of electric heaters :-)

The best tests are practical tests, when your ass is freezing.

This is the first time I've ever put a load of that magnitude
on the wiring.
