An ongoing thread elsewhere is discussing wires and cables, and which is
which. To me, the mains flex on a table lamp or the T&E behind the wall
are cables, both containing two, three or more wires. Correct?

But that introduces flex. Perhaps a cable containing multi strand wires
is a flex, not a cable whereas a cable containing single strand wires
really is a cable? So a telephone cable really is a cable, as is
standard T&E.

What about figure of eight profile bell wire? Two multi strand wires,
moulded together, a flex, or is flex really only an abbreviation of
flexible cable?

Non electrical multi strand cables? Are they really hawsers?

Cable means something with conductors & insulation. Flex is short for flexible cable, and describes the use of stranded conductors. So:
T&E, bell wi non stranded conductors hence cable.
lamp flex, phone lead: stranded conductors hence flex.
Lead means flex or cable with connectors fitted at the ends.
Non-electrical wire I know far less about.

PS before wire there were chains. Circuit diagrams from the very early days were pictorial drawings and showed chains & bars as conductors.

You might be over thinking this :-)

The terms are generally too generic to have a precise meaning without
further qualification.

So for example, a cable might be stranded, wound round a winch, and have
a hook on the end. Or it might be electrical, have multiple conductors
and insulation.

A flex is indeed a shortening of flexible cable or flexible wire, and
normally implies a stranded construction. However a 6mm^2 T&E cable is
also stranded.

A "lead" normally implies a made up length of something with
terminations on the ends. But you would you could for example ask for a
TOSlink lead which has no electrical conductors. It would also be fair
to talk about a HDMI cable, or cord, or wire.

We use 4mm leads & 2mm leads which are a single conductor in an insulator, we also have test leads on our meters, and we have BNC leads (single core+ screen) , and IEC leads we used to have phono leads too, all have insulation.

I tend to use the term cable for a piece of multicore wire that isn't terminated by a connector of any type. Which nicely means I can buy a reel of cable, or a reel of wire which is single conductor.

But we do have extention leads and extention cable, but no extention wires.
But I do have USB leads and USB cables.

Our problems come when we have to describe the differnce between solder with lead and a lead, and why our 4mm leads measure longer than 4mm in lenght.
And then the differnce between bolts and screws, and roundheads, cheeseheads, countersunk, hex, allen, torx, star washers, shakeproof washers.
I've heard some people use the word lead for the thing they put around their dog to take it for walks.
Some nick lead off of church rooves too.

The most recent problem was last week when a research student asked me for some magnet wire. Apparently this in the new name for what I've been calling enameled copper wire. I was then asked is that the same as transformer wire.
He then asked me (looking at the label on the 35+ year old spool[1] of wire
why don't they put the diameter of the wire on the label and what does 38 swg mean.

[1] it's not a reel it's a spool ;-)

I agree.

BS 7671 is great at not defining such things. It does have "Flexible
cable. A cable whose structure and materials make it suitable to be
flexed while in service." But apart from that it leaves people to read
cable and wire naturally - where IMO "cables have wires in them" just
about sums it up.

Then of course there's the verbs. Most people refer to "wiring a house"
rather than "cabling a house". And BS 7671 lends some support to that with:

"Wiring system. An assembly made up of cable or bus bars and parts which
secure and, if necessary, enclose the cable or busbars."

So a wiring system doesn't necessarily have wires in it. Not a lot of
people know that

Since its a made up lead with terminations, then I would suggest its a

Cable means something with conductors & insulation. Flex is short for
flexible cable, and describes the use of stranded conductors. So: T&E,

T&E used to have stranded conductors 3/029- 7/029 - 7/036 etc. Cable for
drawing through conduit has gone back to being stranded.



I was not aware that conduit cables (singles) have ever been anything
than stranded.

FYI T&E has class 1 and class 2 conductors....

Class 1 is solid and class 2 is stranded.
Class 1 is usually up to 2.5mm and class 2 is greater than 4mm.
However you can buy T&E with stranded 2.5mm, either as the cpc (eg
6mmT&E) or as a a 2.5 T&E (cpc is solid)

It's stranded but not flexible, the strands are too thick for that. Hence it's cable not flex.

But it's not a flex!

Indeed, because while it is to some extent flexible, it's not flexible enough for use as a flex. It's just flexible enough to make getting it into its fixed position easier.
