    The subject of the post is the question: what wire cross-section should be for a 12V 10A installation, 2 meters long.
    Thank you for your help.

    If you give 1.5 mm it will be perfect.

    Continuous or instantaneous load, wire loose or bundled? 4 to 6 A per 1 mm? is assumed. I would recommend 2.5mm?, since this length will not add up to much of the cost.

    If it is a copper wire, it will have a voltage drop of almost 0.5V (from the source to the receiver):
    ?U = (2 o 2m / (56 (m / (? o mm? ;) ) o 1.5mm? ;) ) o 10A = 0.476190 ... V
    ignoring the power losses in such a 'conductor'.

    Rather continuous work for me - two hours of work followed by an hour of break and the cycle repeats itself all over again. Free-lying cable.
