TECHNICAL INFORMATION
The American Wire Gauge (AWG) is based on the principle that
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 greate
r fl
exibility in comparison with solid wire.
Stranded wires are made of multiple, smaller-gauge wires
(higher AWG number). 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 b
ut diff
erent
numbers of wire
s diff
er in cross-section. For instance, an AWG
20 strand of 7 AWG 28 wires has a cross-section of 0.563 mm
2
,
while an AWG 20 strand of 19 AWG 32 wires has a cross-section
of 0.616 mm
