The ground wires in that picture appear to be in bare copper, borne out
by the person using a multimeter with a probe resting on the ground
wire. If so, that's pretty shoddy. What's to stop it coming into
contact with the exposed hot and neutral screws on the outlet body as
the outlet is pushed back into the box?

UK wiring regulations require earth (ground) wires to be sheathed in
green and yellow sleeving where it is exposed.

Also, the screws are pretty well recessed (on decent quality sockets
anyway) It's difficult to touch them with a finger accidentally.

Maybe it would have been better to have one 625 line network on VHF,
like most other countries used until analog closedown.
Of course going from 405 to 625 would have meant ther was no room for
two networks there.

The original plan, drawn up in the early '60s, was to re-engineer Bands 1
and 3 for 625-line operation once the 405-line service was switched off; but
it never happened. I guess that the powers that be thought that the spectrum
could be more usefully used for other purposes.

Yes, connecting screws each side of the socket.

Completely open as well not shroded at all. Don't like that, damaged
cover plate and very easy for little (or not so little) fingers to
make contact with a live screw.

The launch of BBC2 was PLANNED for April 20th 1964 but a fire at
Battersea Power Station blacked out large areas of west London -
including the Television Centre - shortly before BBC2 was due to start.

In fact BBC2 *did* launch on April 20th, from a news studio at Alexandra
Palace, I've seen the recording. Not suprisingly the headline news item was
the power cut!

OK so a brief news programme wasn't what the BBC had in mind for the 'Grand
Opening' of BBC2, but a programme was broadcast on BBC2 on April 20th.

As a result, BBC2 opened at 1130 on April 21st 1964 and the first
programme was Play School.

No, the first programme on BBC2 was a news bulletin, on April 20th.

So why were we told that one of the great advantages of 625 was that the
interference would be black?

Yeh, that little backward area called "London" is one of them.

Oh, I don't go there. The natives can be rather peculiar I'm told.

When 405 ended most of us couldn't even remember it.

Unless you have unusually long cable runs or other special factors, it's

Better oversized than undersized, especially if the run is long.

Then why not use 2.5mm? 4mm?

Tables and guidelines are readily available to help you choose the correct
cable for your individual requirements. But in general 1mm is just fine
for a domestic lighting circuit protected by a 6 amp breaker.
