In Reply to: Re: is it safe to pass 2.55amperes along a 20AWG teflon hook-up wire? posted by Gingertube on April 17, 2007 at 00:29:35:
Just a thought, but aircraft spend most of their powered time travelling fast through cold air. Or are those figures valid for sitting on the ground for hours?
Follow Ups:
These figures cover all occasions - The undefloor areas of aircraft can get really hot. Inverters, Transformer Recitifier units,Inertial Navigation Systems, Control Electronics etc all have to have 70 degrees C operation capability and the wire specs are 100 degree C derated values.

I surely hope they put in enough of a safety margin to account for global warming :-)
I'd be more concerned about cold flow. That wire is certain to cause shorts in a few thousand years.
