[ARC5] Why Don't They Melt?

[scottjohnson1]

Don't  plan on running one of those converters at more than 50% of the Chinese rating, which is figured about like vacuum cleaner horsepower or car audio output power (80% BS factor)Scott  Sent from my Verizon, Samsung Galaxy smartphone

        In terms of ohms/foot, the resistance is negligible.

    I have a project brewing which
        requires 32 Volts 
        at 10 amps.  I intend to use a 600 Watt DC/DC 
        converter which will input anything from 12 to 60
        volts unregulated and output a constant 32 volts.
        Here's one such:

        If I input 12 volts, I'm gonna need about 26 amps plus or minus
        to get 32 volts at 10 amps out.  That's half the rated power
        this thing specs.
        
      Trouble is- Look at those input and output
            connectors.
            How on earth can one pull 320 Watts, much less 600, through
            those little screw terminals??  I'll probably go 28V in just
            to knock the input current down to something reasonable.
