A two-pole 30 amp breaker keeps tripping on a brand new dryer and is tripping more often as time goes on (was originally tripping every few weeks or so, now doing it every day), so I figured it would be worth a shot to just replace the breaker and see if that fixes it or the source is something deeper.
Unfortunately, the main panel doesn't seem to have a main 100-150 amp breaker or is a split bus, as I flipped all the breakers on the top half of the panel but the dryer was still live. It looks to be hooked up straight to the meter, so I don't think there's any sort of main switch upstream.

That's not a split bus (Rule of Six). For one thing, it is too new - Rule of Six panels were outlawed before CH panels started getting branded Eaton. For another, all the breakers are accounted for, there would need to be a "Main Lighting" breaker.
By the way, CH is a great panel.
I wonder if the main panel used to be here, and is now on the other side of the wall, and this one was installed as a subpanel to handle the dozen or so circuits that were impracticable to route to the new location.
