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?
Hadn't thought about leads. A lead contains multiple wires, all multi
core (?) so a lead is the same as a flex or cable - or is a lead a cable
with connectors fitted?
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.
