I walked away from that thread, and have not been back on it since, so lets review the facts; you spouted misinformation, and I did give you the "correct answer" right out of the gate, your ego was just too big to acknowledge that you were mistaken. You stated an example of a 6' power cord carrying 22.7 amps @220v to a hypothetical toaster, and you stated that if you put "that same 22.7 amps" through that cord at 25V DC it would heat up and melt. This went against everything I thought I knew from studying and working with electricity for over 20 yrs, but because of your background I asked for your logic behind the statement hoping to learn something new. You proceeded to give hints to irrelevant electrical phenomenon ("Pay no attention to that man behind the curtain!"), which basically showed you had no sound logic behind the statement, it was pure MISINFORMATION, on a thread that is there to inform people. Despite all the facts, documented sources, personal experience, identical online discussion, and AMPACITY CHARTS I linked, coupled with the fact that you actually had to ask me what the term "ampacity" meant, which was the basis of the entire discussion, you continued to deny it yet produced no valid theory to support your false claim. I then bowed out of the debate, knowing that it was likely anybody that was following now recognized the original statement(Oh I'm sorry, "detail") was bogus.
Clearly I did give you the CORRECT ANSWERS, right out of the gate, including (but not limited to) the fact that-
*DC amps and household RMS AC amps produce the same amount of heat
*The ampacity of a wire has nothing to do with the voltage type or magnitude of voltage (save for extreme cases far outside of this discussion)
*The only relevance in this case of the length of wire was voltage drop
And because you still can't accept it, I just made this little video for you, of a 7', 14gauge appliance cord rated at 18 amps/300v AC, carrying 23 amps @23-24v DC for over a half an hour and barely getting warm, proving beyond any reasonable doubt IMO, that you were full of it.
You blocked me because I am the one person here who threatened your ego and credibility in the world of electrical theory and it's practical application. Now Doc, I guess you can't even see this right now from way up there on your pedestal, but maybe somebody will be kind enough to forward it to you.
