New one to me.
Had a breaker go bad. I remember it once when I lived with my parents - maybe middle school age. Same basic result. Ruined day, chasing around a specific breaker... At least I had the internet.
Find your specs before you go, too. I have a Siemens box, but there are multiple Siemens. I bought two, and still wasn't convinced I had the right one til I got it in.
A couple spare 15s and 20s should cover your lights and outlets for the better part of a lifetime ($5-$10 each). Then bigger ones (30/40) for individual circuits like stove, dryer, well, AC.
Having to go out for them is bad enough. Not being able to would be even worse!
