Probably a bad/loose breaker/buss bar connection that arced.

But, that is just a guess.

Thanks Gunnar. I will just get sparky on the job in my report.

This house has alot of other issue with the electrical systems and just about every thing else for a 20 year old home.

That's my guess too. I've seen that before, with that being the cause.

I believe we had a similar photo on another thread recently showing the same thing, looked quite similar ... like it could be the same manufacturer panel.
