Came across this today as I was fire marshaling the afternoon away.

Sorry about the "phone" pictures.

So the heat eventually caused the SEC to melt and detach.

Was it a loose connection that caused the overheating in the first place?

Which brand? Thermal feature had to fail. Plenty enough heat to trip a functional breaker. Somehow, I suspect loose connection alone isn't the full story.

FWIW, beige color of handles looks like Cutler Hammer to me.

Maybe the loose connection was at the bus bar connection in the middle. There's a burn mark there as well.
