Multi core cables

I have some multi core cables but the size wasn't given. The written wire size in the insulation cannot also be seen. Is there any way to find the actual size of this multi core cables?

Do the number of cores will be determined by the number of wires in a cable? Example: a 1 cable consist of 3 - 14 sq. mm and 1 - 5.5 sq. mm therefore this is a 3 core cable? Is my orientation right?

Thanks for answers. Here are some pictures.

We would call that three wire cable plus ground.
In the bottom picture is four wire cable plus ground.

14mm² = #6 AWG and 5.5mm² = #10 AWG.

That's some pretty hefty cable.

How should I know the cable size of one multicore cable?

Yah, a hefty cable, this will be used for an industrial installation.

I run into that problem a lot. With experience you get to recognize the sizes of wire just by working with them.

Is there anything printed on the colored jacket on each wire ?

There are some prints but no trace of size. All I can see is THHN type. Question, Is the colored jacket wire the same size with a single core? I mean the one wire from the multicore is the same size with the single core cables?

I'm not following what you are asking.

Are there ANY numbers at all on any of the jackets. Sometimes a multiconductor cable is assigned a particular part number.

Our cables are marked on the outside jacked of the overall sheath of the cable. In your case it would be on the outside of the black jacket.

It appears you have samples there. If you had an entire roll/spool of cable it would likely be labeled.

Just grab some calipers or a mic and check the actual dimension of the copper. That should quite easily tell you the AWG or cross-sectional area by comparison to any number of wire size charts on Google images.

Usually the ground wire is not counted in the total number of conductors/cores in the cable. However sometimes it is when the ground is insulated, like yours is. I suspect the naming practice may vary by manufacturer and whether or not they are selling this product as a "cable" or a "cord".

I would call the one in your hand a "four conductor with insulated ground".

This is my next step to identify the cables - by using caliper. Well explained sir. Thanks.
