DC breaker markings?
Have just noticed ++ next to the screw at the lower, or "open" end. I'm not an electrician, forgive me my ignorance. DC breaker is normally installed in the + wire anyway, so what is this cryptic ++ ...

Thanks, Guys! I opened this thread idly, just for something to look at and it's really helpful!
So the +++ on a DC Breaker is what "Line" would be in AC wiring, correct?
Now let me try a question since you seem to be UP on this stuff: Same true of AC Breakers? I don't much care for the way our IOTA Load Center is set up. It's Converter/Charger, AC Breakers and DC Fuses all in one. AC portion uses 2-in-1 breakers. Its four branch circuits are "15/15" (each protecting two 15A branches) but Main and A/C are protected by a "30/20" with 30A being Line into the Panel and 20A protecting the A/C. This means the 30A side is being fed through what's normally "Load"(the screw terminal) and powers the box buss through what's normally "Line" (the stab down terminal). Is this actually acceptable? I suppose IOTA got some kind of "approval" for their design, but it sure makes me wonder.
And... I really don't like the 2-in-1 breakers, especially the 30/20, in that tight space. The RV runs right at max in summer with A/C so both sides of that 2-in-1 are close to capacity. I think the 30/20 is getting warm enough to cause false tripping. What do you think?
