You'd think that if there was a short/arc that it'd happen nearly instantaneously of turning the power back on. @Bryce I guess in theory I could have missed something, but these are non-cluttered rooms so it's pretty easy to tell if something is plugged in or not. The only thing that isn't unplugged is the lights/fan and neither of them are on nor were they on when the power went out. | |

Arcs can occur without load (hot to ground, hot to neutral). It's possible there was a surge along with the outage that could have caused this, or at least have worsened an existing condition to the point it is now a fault. | |

I figured that's probably the scenarios, but I can't figure out why the breaker keeps working (for 45 seconds) or how an arc would have shown up, suspiciously after a power blink, especially when there's nothing pluged in/turned on | |
