@Firlefanz Makes sense.And yes, it was annoying, but also (to me, with just enough knowledge of how this stuff works to be dangerous) *really* weird. In my case, had it been a wiring or load issue, just replacing the breaker with a same-type shouldn't have fixed the issue let alone moved the issue to a *different* breaker; and not once, but twice.By the third one I just decided that it was easier to just ask the electrician to replace all of them and see if that would help.
