A breaker may trip because a circuit is overloaded, an appliance is faulty, or a wiring fault is present. Repeated trips should not be defeated by repeatedly resetting the breaker or replacing it with a higher-rated device. The cause needs to be understood.
What to consider
Notice which devices were operating, whether other rooms are affected, and whether the breaker trips immediately or after a period of use. Do not open the panel or inspect wiring yourself.
Practical next steps
If the breaker repeatedly trips, will not reset, or there is heat, buzzing, smoke, or a burning odor, stop using the affected circuit and arrange qualified help. Any sign of fire or smoke requires urgent action.
When to seek qualified help
Electrical faults should not be diagnosed by trial and error. Do not bypass protective equipment, open electrical panels, or work on energized wiring. If there are signs of smoke, fire, arcing, or immediate danger, move away and contact the appropriate emergency service.
Requirements and recommendations depend on the equipment, the installation, manufacturer instructions, and applicable local rules.
