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 ++ ...
Forum Discussion
The + is the higher potential side (PV input or Charge Controller output).
When MidNite Solar was doing ETL testing on the line of breakers you are using, they wired a breaker incorrectly and it melted down in the closed position! (Luckily, they had a knife switch in the circuit.)
