One of the pictures in the Amazon description seem to make it pretty clear to me. Top right of the breaker has the Pos. connection coming into the breaker. The terminal exactly below that would the Pos going out to the load. The other terminal at the bottom would be the return wire from the load (Neg lead), and the top terminal on the left would be the Neg lead going back to the source.
Did you look at all the pics for that breaker. There are arrows showing direction of current flow along with colors indication polarity....Red coming into the breaker and Black returning to the source voltage
Yes, I did. Say, take a look at this picture. Notice on the + side of the breaker there's a small diagram. That's where I see the diode.
DC breakers like this one, many times have "magnetic blow out coils" inside them. With Direct current, there is not a voltage zero crossing point like there is in Alternating Current. Because of that, when a DC circuit is opened or interrupted, the arc is much harder to extinguish, so the magnetic blow out coils force the arc to extinguish quicker than if they weren't there. Polarity matters in order to make the blow out coils work properly.
See my post #3 for the answer!
You might be right....but I'm need to be sure.
If it makes you feel any better, I've been a Journeyman Maint Electrician since 1980. Thirty years of that work history was in a large Steel Mill with hundreds of overhead cranes. Two things about those cranes.....probably 95% of them ran on 250VDC. We had six overhead cranes that had a lifting capacity of 400 Tons or 800,000 lbs. I've worked on DC equipment for the better part of my life, so just a bit of experience there. Every single one of the the huge DC contactors for DC motor control of the cranes had arc suppression via a blow out coil and an arc chute to help direct the arc away from the contact tips.....one of which was a stationary contact and the other a moveable contact. Obviously those were/are much larger than the tiny coils inside the breaker that you are looking at, but the same electrical theory applies to both.....just that one of them is on a much larger scale and the other one.......tiny stuff.
Do you mean "consensus"? In further reading you might be correct. I discovered that the side of the breaker that has MORE power to it should be connected to a specific side of the breaker. The side of the breaker that'll be presented with LESS power should be connected to the remaining side.
If you are hoping to find intelligent, knowledgeable, and accurate responses on the question section of Amazon replies, your odds are way less than 50%....if even that high. This forum is filled with people who have in many cases, years and years of experience with electrical equipment, engineering degrees in some instances, and a desire to help those who truly want/need help. I know where I'd place my bet. ?
