The American Wire Gauge ꢀ AWGꢁ is based on the principle that
Circular wire
Cross-
Limit temperature
2 mm / 2.5 mm2
1.6 mm / 1.5 mm2
the cross-section of the wire changes by 26% from one gauge
number to the next. The AWG numbers decrease as the wire di-
ameter increases, while the AWG numbers increase as the wire
diameter decreases. This only applies to solid wire.

However, stranded wire is predominately used in practice. This
has the advantage of a longer service life under bending and vi-
bration as well as greater flexibility in comparison with solid wire.

Stranded wires are made of multiple, smaller-gauge wires
ꢀ higher AWG numberꢁ. The stranded wire then receives the AWG
numbers of a solid wire with the next closest cross-section to
that of the stranded wire. In this case, the cross-section of the
stranded wire refers to the sum of the copper cross-sections of
the individual wires.

Accordingly, strands with the same AWG number but different
numbers of wires differ in cross-section. For instance, an AWG
20 strand of 7 AWG 28 wires has a cross-section of 0.563 mm²,
while an AWG 20 strand of 19 AWG 32 wires has a cross-section
of 0.616 mm².

The wire cross-section shown in the legend was connected as test cable. In the case of
multi-position connectors and cables, the heating is greater than it is with individual con-
tacts. For that reason, it is calculated with a reduction factor.
For connectors, the reduction factors for multi-core cables pursuant to VDE 0298-4:2013
are applied. The reduction factor is factored in at 5 live wires and up.

DERATING CURVE
The corrected current-carrying capacity curve, derived from the base curve determined
ꢀ 0.8 x measured currentꢁ. It factors in manufacturing tolerances as well as uncertainties
in temperature measurement and measurement arrangement. See derating measurement

The metrologically determined current which is permitted to flow continuously through
all contacts at the same time and will increase the contact temperature by 45 Kelvin.
The amperage is determined according to the derating measurement method
ꢀ IEC 60512-5-2:2002 ꢀ DIN EN 60512-5-2:2003ꢁ and derived from the derating curve.
