Note that this is a very different measurement to standard millimetre diameter.

Square multiply by itself the diameter of each strand 0 32 0 32 0 1024 multiply this result x pi 3 14 0 1024 x 3 14 0 321536 divide this result by 4 0 321536 4 0 080384 multiply this result by the number of strands 0 080384 x 14 therefore the approximate area for 3mm auto cable is. These are mostly used for appliances and objects that require much more electrical power to operate or special use situations. Showing cable size in mm this page shows the comparisons between the amperage of your circuit and the gauge of the wire require to carry the current. Cable sizing selection chart step 1. Correct cable size select the correct circuit type.
