[sdiy] Wire gauge vs resistance

[harrybissell]

Hi Magnus

what do YOU know about 26ga wire ???   :^P

I run 2000A through a 26ga wire all the time.  You can't even GET
that much current through the wire (its resistance is too high) the best I've
done is 100A through the wire (for 10us... oh yeah you DID mention time, didn't
you :^).

This is to test that the power supply will shut down if shorted. The wire does not

even get warm. Should the shut down fail, it gets 'open' instead
