The UK used several systems, and a friend of mine who traveled to London
in the 1970's found that there were four different electrical systems in use
in various parts of the city. By that time they had been standardized to
240 volts 50Hz, but the older plugs and lightbulbs (different ones for
different systems) remained.
Your friend sounds confused. The 240/50 was standardised a long time
before 1970, and the various plugs and bulbs had been running on 240/50
for some decades by then.
I remember a major upgrade taking place in West Ham to upgrade the
distribution network from 215V AC to the standard 240V while I was at
school there in the late 50s.
Nearby Ilford still had 200V DC, a hangover from when Ilford town
council generated 600V DC for its tramways and obviously found it
convenient to stick to DC for domestic supplies.
When it was converted to 240V AC I do not know but there was no evidence
of anything remotely DC connected when I moved there in the early 70s.
In the US there were 25 Hz buildings and even houses as late as the
early 70s and a few DC apartment and office buildings in New York
later than that. I stayed at a swank highrise in Chicago in the early
70s that was AC by then but was originally DC and there was evidence
of it in the labels tacked in the fuse box.
We also had a little 50 Hz before the war.
I've always wanted to do a full study of DC and odd frequency power
historically in the US but the research is not helped by the
electrical utilities. I think they are ashamed of it.

We mix our units much more than that. Take temperatures - if it is
near freezing we use Centigrade, when it is hot we use Fahrenheit.

Yes, people used to be taught things like spelling and multiplication
tables in school. I used to get my pocket money in shillings and pence,
occasionally shops would give change that would include farthings, and I
don't recall having any problems with this.
It was a world in which spellcheckers and calculators hadn't been
invented yet, and in their spare time, brainrotting electronic gadgets
like MP3 players and video game consoles not having been invented yet,
people would sometimes read books. We grew up in it and got used to it.

Thanks for confirming we can add flex ratings to the things you knowYes pet, a 15amp breaker has the same rating as 30amp breaker if
you say so... One is far more likely to have an appliance lead
that is rated at 15A, even for appliances that have internal 1amp
fuses, rather than such an appliance having a lead that one could
run a domestic -four ring, grill and oven- cooker off...
Wonder how you know all this? Just who ever wants to draw more than 13The great advantage of radial circuits is that idiots find it a
little more difficult to bridge out the breaker in the panel,
unlike the silly fuse fitted in BS1363 plugs (which for some
silly reason is the same shape and diameter as many screws, bolts
and any other round bar)
You obviously haven't read them. And certainly don't understand the basics.: 'The same hardware' as used for radial circuits is not suitable
for final
: ring circuits. As I keep saying, you need to learn some
fundamentals
: instead of making a fool of yourself.

Hmm, if correct then every spur off a ring circuit is breaking
the regs!
All you have in your place is electric fires and table lamps? Explains itYou still can run more that three 3Kw electric fires off each
ring circuit, thus how many of these sockets are for power and
how many are basically going to be over spec floor/table lighting
points[1]?
