How does the replacement look now? Look carefully for cracks and feel the smoothness of the new breaker in the places the other one failed. Not sure about your situation, but I have seen Bakelite body terminal strips give out because the mounting holes were ever-so slightly misaligned. Tightening the mounting screws for the terminal strip didn't break the strip but it did stress it so that normal usage eventually caused failure. If the mounting hardware didn't slide into place easily or wasn't perpendicular to the mounting plate, then tightening the mounting nuts may have set up internal stresses that were later released by your collision. It would be harder to develop that stress in a more flexible or more compliant base, like wood or lexan.

This, is why all of our electronics are secured via Zip Tie, and not solid mounting hard-wear, its faster, easier, as secure.

The breaker and the cRIO are the only things that we dont have ziptied down. Im still not 100% sure it was because we got hit hard a few times. But it is definitely a possibility

First it was the digital sidecar at Peachtree, now a main breaker in North Carolina.

If you guys make Einstein, I'm bringing a fire extinguisher.
