My mind is boggled!I of our guys saw this today. Lady who lived there had no idea how long it was this way.
How can even a DIY nincompoop look at the disparity in the conductors on either side of that breaker and not see that something ain't right here?

I had the same thought.This proves that table 310.15 B6 needs some tweaking.

Looks like the original main breaker failed and was replaced with non-standard methods. However looking at the load side conductors, there is no evidence of any heat damage so the total load must be small.
Sure, if there was enough current, but there wasn't even enough current to discolor the white insulation. Just an example of how conservative the Article 220 load calculations really are.Maybe a fused link?
