6.2.11 American Wire Gauge (AWG)
The conversion table puts into an exact relation the American Wire
Gauge (AWG) number with the cross-section measured in mm
2
.
The first column reports the AWG number, the second the
corresponding diameter of the cable in mm, while the third reports the
equivalent cross-section area in mm
2
. The table shows some
examples of cables available, and their characteristics. To ensure
safe margin, specified data for the type to be used must be achieved
and entered in the calculation tool.

Note that this table shows one wire of the pair only. This single wire
data shall be entered per cable segment in the PowerCalcTool, and
the tool takes into account the loss of the pair of cables, plus the unit’s
internal connection loss and safety margin.
