However, it's advisable to wait a few minutes for the appliance causing the overload to cool down before resetting the breaker.

Can a tripped breaker cause a fire?

Tripped breakers are designed to prevent overload or short circuit conditions that could lead to overheating, electrical fires, or other safety hazards. However, if a tripped breaker is ignored or if the underlying issue is not addressed, it could potentially lead to electrical problems that increase the risk of fire.
