Burnt bus

Looks like heat damage to me.
And in unrelated news, I don't see many 150 amp main disconnects.

Given the limitations of inspecting via a photo, I wouldn't judge this one worthy of mention.

I agree with Marc, but as he said, there are limitations to what show up on a pic.
I've heard from electricians that many bars are discolored prior to installation.
Here are some recipes for discoloring copper: http://www.sciencecompany.com/...ulas.htm

This is a 2826 square foot, single family home built in 1998.
I don't think that would be a copper bus, would it? It is possible with a house that size, that the service is somewhat undersized, which could certainly lead to overheating of the bus. With just the one pic to go on, I'd call for a more thorough check of the panel by an electrician.
Allseason, you should rename your pics before you post them.

Sure it could. There are still lots of bare copper buses out there.

Except that, with a 150-amp main breaker, normal use is unlikely to cause the bus to overheat. That bar can conduct a heck of a lot more power than 150 amps. And if the service were to draw more, I'd expect the main breaker to trip after a while. If the discoloration is caused by overheating, it's probably because the connection is loose.

I don't see copper, though. In my area, I'd be surprised to see bare copper buses after about 1970.
I mean Copper like in these pics.

I've never seen a copper bus panel in person, but wouldn't all the buses be copper? The panel in the OP has aluminum SEC, aluminum lugs, and aluminum straps from the mains to the branch circuit buses. I still think it's smoked.

If the bus in the panel shown in the OP's pic had overheated the plastic behind it would have melted /deformed, it's nothing to worry about in this case.
