BS7671 permits the use of other colours as long as the ends of the wires
are
clearly labelled "L1", "L2" etc. I guess the installers simply didn't have
any grey cable.

No, this is an armoured underground cable with cores in the colours
stated.

Then it doesn't conform to EU harmonised colours.

L1 is brown, yet your picture has "negro" against L1, so I'm not sure that
we can place any confidence in its veracity.

Here's another photo, since you seem to have trouble handling the truth:

The "truth" is that the harmonised colours for three-phase are brown, black

and grey. If anyone is having problems handling the the truth then its you
I'm afraid. The photos only tell us about the one installation, who says it
conforms to the harmonised colours?

Its quite possible that the colours written-in are old pre-harmonisation
Spanish colours.

I've never actually come across it. Is it actually used?

Do you think there are still analog TV transmissions in Belgium, a
neighboring country whose capital is less distance (198 miles)
away from London than Edinburgh (332 miles)?

RTBF ceased the last analog TV transmissions on March 1st, 2010.

I think the government made the right decision, the limited VHF spectrum

? - one on band I and at least one on band III, surely? I lived in
(West) Germany in the 1960s and '70s, and I'm sure we could get at least
two channels on band III (yes, I know B and G channels are narrower, but
not that much).

There were some areas with two band III channels, Brussels for instance
on E.8 and E.10. With a bit of luck you could get a Dutch channel too or
a Frech one in the South. We got three Band III signals in Brussels
around 1966 (Belgium French and Flemish as well as France).
This of course would not have meant that full area coverage like the
whole of the UK would have been possible.

Holland had only one channel on VHF, partly because Belgium needed two
in Brussels. I think most of Germany had only one too, except if you
were close to the border between West and East (or Berlin).

For the UK two channels was possible using 405 lines because they used
narrower channels, leaving room for more channels to allocate to
transmitters. Even then, different polarization was often necessary to
separate the signals.

The same was true of cable systems. As TV sets were incapable of
operating with adjacent channels, they carried only alternate channels.

Dutch cable tv provider Casema used a scheme like 24 28 31 35 38 42 etc.
Interference products tended to be out of the used channels.

When tv sets became better over time many more channels were used,
including most VHF channels.

You make it sound like 'we' were forced to adopt another country's

Flex colours were originally changed to harmonise the sales of electrical
goods across Europe - in the same way as our electricity supply became 230
volts instead of 240. Without changing a thing. ;-)
The flex colours were chosen so a colour blind person could still
differentiate between them - if, of course, he knew that the dark one was
line...

Permanent cable changed quite recently to the same colours.

Three-phase wiring has been harmonised from red, blue and yellow for the
phases and black neutral to brown, black, black and blue neutral. Yeah,
I know...

Red(L1) Yellow(L2) Blue(L3) now is Brown Black Grey

Were both channels available nationwide or just in densely populated
areas?

I can't remember, I'm afraid. I was only 10 +/- at the time! ISTR
"German one" - ARD - was the one on band I, and was pickable-up where we
were (Dortmund, then Muelheim) on the proverbial wet string, and was a
painfully clear picture. I _think_ we could get more than one on band
III.

Or is German topography more amenable to providing large area coverage
with fewer transmitters?

It has as varied topography as the UK, I would say.

(I'm thinking here of the German plains that we were told for many years
provided ease of access for Soviet tanks ...)

There were indeed such plains east of Dortmund; our lot* went there a

lot for exercises. I think they were (are) fairly sparsely populated,
though, so less germane to these discussions: big agriculture area,
IIRR.

Yes - green/red being the commonest form of colourblindness. Though
making one stripy meant anyone could get it. (A physics master - I think
it was - once told me: brown is what you'll go if you touch it, green
and yellow think buttercups on grass i. e. earth.)

Old German (flex - I don't know about house) colours were red, black,
and grey - I can't remember which was which. I have an old globe with
these colours.

phases and black neutral to brown, black, black and blue neutral. Yeah,
I know...

It _does_ seem odd. Not only the change keeping black but for a

different purpose, but also having _two_ of the phases the same colour.
(If that _is_ truly the case and not one of them grey, as some have
claimed in this thread.)

Though on the subject of motors turning the wrong way etc.: is it
definitely true that you always get the same phase relationship between
red, blue, and yellow? (And what happens at star-delta or delta-star
transformers: are the outputs still coloured red, blue, and yellow?)

Tables and guidelines are readily available to help you choose the correct

for a domestic lighting circuit protected by a 6 amp breaker.

15A is the smallest in use in the US, exept in industral machines.

You could say the same about analogue TV. Doesn't make 525/60 NTSC better

Analog TV, what's that? ;-)

AFAIK, we haven't had analog TV broadcast anywhere in the US since June
2009. I know that in theory, US broadcasters have into 2015 to make the
switch, but in reality the switchover was highly pervasive on the first day
possible, not the last.

Look again. Some low power transmitters still transmit NTSC. There
is supposed to be one withing range here, but I can't get any TV signals
since the switch.

Something that can actually be enjoyable, useful and even a bit educational,

A capacious 2 channel DVR is a big help.

An internet ready BluRay is better. A lot of free TV via the

Erm, 405 started before the war and was alone until 1964? Then it
continued for another 20 years?

Someone said the last two years of 405 line signals were generated by an unusal
method, I think the word they used was "endearing". What was it?

BTW, the BBC shut down TV broadcasts in for World War II, and resumed
them at the exact point in the same broadcast after the war.

That's very easy to do with film. I should know. I loaded and ran
truckloads of 16 mm film on a pair of RCA TP66 projectors in the '70s.

I don't know how well UK sets worked in the 1960's, but US TV sets were
not capable of receiving adjcent channels at one time, so they were not
used. For example, channel 2 was used in New York City, while the nearest
channel 3 station was in Philadelphia, 90 miles away and too far to be
received without a large antenna.

Those '60s TVs worked fine on CATV, with no open channels. Even sets
from the '50s work well that way. Early CATV was simply 12 VHF channels
deilivered to the TV at 0 dBm to +5 dBm. Some super cheap sets with a
single IF stage and no RF stage didn't work well, but they were the
floor sweepings of the industry and intended for markets where there was
only one or two stations. 'Madman' Earl Muntz made some real crap.
