Radios of that era had a setting named \"phone\". And a socket. You

Every mains valve radio had a \"Gram\" or \"PU\" socket with switching,
usually combined with the waveband switch.

Every AC tube radio....

Never heard of chirps? It\'s a mathematical transform of an impulse,
but doesn\'t need the big peak power. Big radars do it so they don\'t
ionize the air near the antenna.

Most critters, humans included, use some form of echolocation.

Look it up. It\'s interesting.


Even blind people do it.

Presumably *especially* blind people, because without sight they need to
develop other ways of detecting the world around them. I\'ve seen videos
of blind people who can describe their surroundings (even places they\'ve
never been to before) almost as if they are seeing them.

I\'ve never heard of a sighted person who has mastered chirping and
echo-location, but then there\'s no point if there are easier ways of
seeing what\'s nearby.

both L&N, takes up only a single slot. Worst case, there is no
discrimination, so either end may trip, but that doesn\'t really matter.


That is interesting.

AFAIK the double pole switching need not be at the CU but can be
installed at the charger end.

You may have a requirement to have RCD protection for the cable to the
charger inside the CU (say the cable cable from the CU to the charger
is buried less than 50mm behind the surface) but you have to be
careful what type of RCD you use for this. Usually a type A RCD will
be OK.

The installer\'s standard installation is apparently to use Henley blocks
to split the feed between the existing CU and a new, 2-way one, with a
double pole MCB in it. They will then use whatever cable is needed to
meet the regulations without RCD protection (T&E or SWA).

The charger incorporates its own RCD protection and monitoring of the
Earth/Neutral), so does not need one on the supply and no earth rod is
needed either. There is no facility for isolation at the charger, unless
a separate, weatherproof enclosure is fitted.

In my case T&E was fine, as it runs in the (indoor) electricity
cupboard, into the cavity (the cupboard is recessed into the wall, so
the back of the cupboard is the outer skin of the wall) and then through
the wall into the back of the charger, less than 2\' away. At no point is
it less than 50mm from the surface, except where it is visible in the
cupboard or completely behind the charger.

I preferred not to have the Henley blocks and second enclosure in the
cupboard, so I confirmed with them that if I supplied an RCBO (type A,
with a C curve), purely for combining the 2-pole isolation and single
slot form factor, they would terminate in my existing CU.

Thanks for that.

Don\'t joke. My dad is in the early stages of dementia: normally he is
fine
but if he gets an infection he becomes more confused. He\'s recovering in
hospital from an infection at present. He\'s right-handed, but when an
occupational health nurse asked him the other day \"Are you left or right
handed\" he answered very confidently, and without a moment\'s thought
\"left-handed\". But then he thought for a moment and said \"No I\'m not.\"
It
doesn\'t help that he knows my mum is left-handed: he could have been
thinking of her in that split second.

Your dad has an excuse, others do not.

I know someone who can\'t tell left from right without touching
herself.

Why, is she asymmetrical?

As a young child, I would just pretend to write.

I\'ve never understood people who get left and right confused.

It\'s blindingly obvious if you\'re right handed, since the words right
and write are so similar.

I can never
remember which of the two is port and starboard (*), but left and right
are
as ingrained in the \"immediate lookup table\" in my brain as counting,
addition and the days of the week are. I\'ve never had to go through the
motions of \"which hand do I write with?\" to work it left and right. Of
course, some people can\'t do the mirror-image processing needed to work
out
that a person\'s right hand is on the left side as you are facing them.

I used to pause with that one but it has just dawned on me that I never do
anymore
for some reason.

(*) I always have to think of \"port red wine\" (to give the colour of a
port
light, starboard being green) and \"port and left both have four
letters\" -
so there\'s a brief period of processing rather than it being
instinctive.

It\'s far easier to do what I do. Port is a shorter word than starboard,
left is a shorter word than right. So I\'ve stored them in the same
place in my memory.

As for bow and stern, stern means nothing to me (apart from someone
who\'s angry), but we all know what a bow-wave is.

I never have to think about that one.
