More on the Bad 40A Breaker
I got some time to test the bad breaker today. Connected it to a regulated laboratory power supply, Sorensen model DCS 20-150, in regulated current mode. Increased the current slowly and saw nothing unexpected until it reached about 30A. At that point its started switching on and off very rapidly. This is consistent with the behavior observed when the bad relay was in our robot.
Seems that we damaged it somehow, or maybe it was bad from the start.
Again, has anyone seen similar 40A breaker behavior?

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
