How much current/power though a specific cable??

[flatlandpilot]

the heat in the wire = I^2 * R
(and is not "aimed" at 220v, the formula works with all voltages)

I was suggesting that the link in your post is not that relevant to the posters original question, that's all.

No please .... feel free to elaborate on this as much as you all want , ... all info is welcome and interesting

Now see what you started! LOL

But as you say, it is all knowledge

in the question was asked for "current/power"

The maximum current for a certain cable is:

0.5mm² 3A
0.75mm² 6A
1mm² 10A
1.25mm² 13A
1.5mm² 16A

you can make the current to power conversion like this: P = I * V
So the maximum power a 1mm² wire can carry at 12V is 120W.

When using a power supply bigger than lets say 10 A (12V)
every wire has to be 1mm² or better else you damage youre wiring
in case of a short circuit, for this reason it's better to use fuses.

flatcables and flatcableconnectors are usually rated for 1A.
