Wire vs Cable
Wire vs Cable
(OP)
Is there an absolute definition of the difference between insulated wire (any type) vs cable? I had previously believed that cable was multiple conductors in a single casing, but have found that frequently single conductor insulated "wire" is referred to as cable.





RE: Wire vs Cable
WIRE: A usually pliable metallic strand or rod made in many lengths and diameters, sometimes clad and often electrically insulated, used chiefly for structural support or to conduct electricity.
RE: Wire vs Cable
Electrical "cable" may be single-conductor or multi-conductor.
Colloquially, it may be bare or insulated, solid or stranded. 10AWG seems like "wire", where 4/0AWG is more of a "cable."
[The IEEE dictionary has much more detail; not transcribed here.]

jag27, your info looks like it came right from a dictionary, and is what I expected. Can you tell me your source.
The particular document that has me investigating this issue, has different rules for wire and for cable. Unfortunately, no explanation for the difference.
RE: Wire vs Cable
if you really want it to stand up in court, you'll need to reference an established (published) document that defines each -- unless you have a vendor's reference, an IEEE document, or other similar item that gives a definition, I suggest your best bet is going to be Webster...
good luck..

“…something that stands up court!” Pooch, are you an attorney or expert witness? Why are you wasting time asking on an informal trade message board?
RE: Wire vs Cable
This should give you the difinitive definitions you need (plus terms such as stranded conductor, strand, stranded wire, and cord)-- but since you need this to stand up in court, you will need to check this out at the Library or purchase the book rather than me type in many paragraphs of definitions...
RE: Wire vs Cable
source. I would like to understand what I'm doing before I present conformance recommendations. Or, worse yet have to field retrofit due to a small technicality. What sucks is that for the most part we don't need to be a part of IEEE, so I can't get the resources easily.

RE: Wire vs Cable
Cable - One or more insulated conductors with or without an outer jacket, armor, or shield.
Wire - A term that can apply to either a single insulated or bare conductor,usually in the smaller sizes. "Wire" is often used interchangeably with "conductor".
multiple conductors - must be cable, not wire.
single conductor - could be either one.
insulated - could be either one.
uninsulated - must be wire.
outer jacket, armour, or shield - must be cable.
no outer jacket, armour or shield over insulation - could be either one.

1. IEEE Std 100 "Dictionary"
There are several definitions of "cable", e.g. (4) Transmission and Distribution:
A cable is a conductor with insulation, or a stranded conductor with or without insulation and other covering (single-conductor cable) or a combination of conductors insulated from one another (multiple-conductor cable).

I think I have a clue as to what new spec is trying to say.
