Generally yes, but context matters:
Safe to reset once:
Occasional trip (first time in months)
Clear cause (overloaded circuit, power surge)
Breaker isn't hot to touch
No burning smell or visible damage
Do NOT reset if:
Breaker trips immediately when reset
Breaker trips repeatedly (multiple times per day)
Breaker or panel is hot
You smell burning or see scorch marks
You don't know why it tripped
Repeated tripping indicates a serious problem—circuit overload, short circuit, or failing breaker. Schedule service rather than repeatedly resetting.
