One should also consider the prospective short circuit current
in that circuit if the standard requires single fault testing in that
circuitry.
(and even if it's not required)
If your wire is connected to a 30 amp power supply it's quite a different story
as when it's fed by a 1Amp
I was just discussing the current handling capabilities of appliance wiring
material and while I have a chart it is of unknown heritage and differs from
some other reference material. For example the chart I have says 26AWG wire can
handle about 0.25 amps, but when I look at the connector it

Ampacity charts (particularly in the NEC) may assume wire pulled in
conduit, more than one current-carrying conductor, etc. You may be better
off using a chart from your product Standard (60950 has something to say on
this topic but it's a bit conservative).In your case, I would approach

A few of the wire vendors have reference charts that may be of use. The link to
one example is below.

This chart should give a rough idea of the temperature change of wires at
different ampacities. This table makes general
