Yes but you need to allow for the wind direction. If the wind is against
the radio signal the pips will inevitably be slightly delayed. This was
predicted by Einstein in his Theory of Special Relativity, and later
verified by the famous Dogg, Biskett, and Münch experimental series,
which involved three radios, a weathervane, and Biskett's dad's stop
watch that he nicked when he'd been an army referee.

But records only go back 50 years.

So you cant say what the voltage was in - say - the stone age.

Especially since kettles only run for a few minutes. I guess the only
real potential problem is from high-power portable electric heaters
(which aren't used so much now)?


You are looking at a 20A load on a double socket for one hour before you
get
problems. The same problem occurs if the socket is on the ring or a spur.

I remember that. How long at 26 A?


What do you plan to run at 26A 92 x 13A) for an hour?

The worst case scenario is still a buggered double socket.

Me? Nothing. But there's nothing to stop someone from plugging two 3
kW heaters in. I agree with you that it's unlikely.

Have you ever encountered caterers? They don't understand the laws of
physics, or electrics, and are quite content to plug in half a dozen tea
urns, water boilers, at 2+KW each and then moan about the crappy
electrics. I've experienced them on outside events too many times to
count.

There's nothing to stop someone plugging a 13 amp load into every socket
in the house.

Except, perhaps, the maximum load the feeder into the house can supply.

So I assume those who continually come up with a 'what if' as regards
final ring circuits and just how horrible they are have taken this into
account? And limited the number of sockets in their house to about 7?

I think its more likely that they just accept that its unlikely that many
will ever have than may 13 amp load appliances available and that
the main breaker/fuse will handle the worst case where someone
does, fine.

Yes. so you say, but analysis of just one pre cambrian battery pack
discovered at the University of East Anglia suggests otherwise.

its deniers like you who give electricity a bad name.

Don't buy a cheap one, you will regret it. Also avoid really cheap crimps.

Err. No we don't! The actual sockets in the UK are still 240V AC (and
in continental Europe are still 220V AC). It's just that the error bars
on allowed voltages has changed (so it's something like 215-245V) - and
all equipment has to cope with that range.

(I'm pretty sure that ARW knows this, but just in case others dont...)

It's remarkable how many don't know that.

It's the reason why we are still using 240v tungsten filament lamps in
the UK (and, doubtless, the same reason they're still using 220v tungsten
filament lamps in most of Europe).

Such incandescent filament lamps are extremely sensitive to variations
in supply voltage in regard to their luminous efficacy and lifetime hours
rating.

230v are political volts, not real volts
