Kees,
I agree. Conservatively rating the wiring lowers resistance drop, runs at
lower temperature, gives stronger connections, is more vibration resistant
(if not soldered), and better absorbs mechanical damage. There are three
reasons to use smaller gauge wiring, cost, weight, and rarely, space.
Aircraft wiring uses smaller gauges for a given load than automobile
practice. Aircraft wire uses thinner higher temperature rated insulation and
the copper wire is tin washed, lowering connection resistance. These
features somewhat ameliorate the higher voltage drop aircraft practice
accepts.

Solid advise, however I prefer to use ca. 2X (or more) thicker gauge wires
than necessary to minimize resistance and thus heat build up, just to be on
the safe side.
