Will the circuit breaker trip after a power outage in the three-level distribution box

While the outage itself does not trip a breaker, the event surrounding the power loss can certainly be the catalyst for a circuit interruption. For example, a short circuit in a device might trip the bedroom. A circuit breaker tripping the moment power is restored after an outage is a common experience for many homeowners. The breaker's safety mechanism is responding to an abnormal. Set up is main breaker/ service panel exterior, lighting and outlets on the interior sub panel. The interior breakers are the ones tripping. If the power company finds nothing wrong, get an electrician out.
