Question Service Panel Replacement

I found rust in my service panel and now hear a "buzzing." I assume it is arcing and I will need to replace the whole panel. Do you think it's worth replacing the individual circuits?

If I do replace the service panel, is it relatively easy, assuming no upgrade and perfect replacement of circuits? I assume I would contact the electric company to safely change the 100AMP circuit as well.

The buzzing is probably just mechanical vibration rather than arcing. See if you can identify precisely where the sound is coming from.

There are many possible reasons why a new panel might be an improvement (e.g., newer, safer brand, more power, more spaces, etc.). If some of these things are desirable, then you may want to replace the panel. However, if none of these secondary benefits apply, you may want to think twice about whether this is necessary. It is neither "easy" nor inexpensive.

Thanks for the information. None of the secondary benefits apply, but I don't think the buzzing comes from mechanical issues because lights also flicker sometimes. Any estimate on the total cost? I was hoping to come under $300-400.

The buzzing might be coming from a breaker that is not fully seated in position. If I were you I would carefully apply a little pressure to the breakers you believe the noise is coming from and see it that helps to alleviate the problem. Flickering lights may or may not be due to the service panel. Could be a loose wire in a box somewhere on the circuit(s).
