2) I'd use 10/3 for the 240v circuits. You may not need it now, but
the extra current capacity is there. The DC will probably never need that
kind of capacity, but at some point, you may put something else there.


Ah, I get it now. Use 10/3 NM cable, but still use a 20 Amp C-B (duh).
No fuse necessary (to protect the equiptment).
