Thank you! So it's the "stickiness" of DC causing these problems, eh? I wonder if there are applications where the DC could temporarily be converted to AC or turned into some kind of oscillating DC temporarily to use more hardware.

>So it's the "stickiness" of DC causing these problems, eh? Yes, but it's more than just sticky in the sense of welded-contacts. A DC Arc is a continuous plasma that is conductive. That means the arc continues even with a significant air gap. The arc stretches as contacts are separated and yet the arc continues. That means that fuses can burn out completely but still conduct. Breaker-switches can trip and then catch fire while they continue to conduct rather than safely interrupting the arc. So fuses, breakers and relays all need to be designed specifically for DC or significantly de-rated compared to their AC voltage and amperage ratings. > applications where the DC could temporarily be converted to AC Yes and that involves an inverter.
