    Re: How much current/power though a specific cable??

    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.

    Re: How much current/power though a specific cable??

    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.
