Breakers limit the current on the conductor to a safe level, too many appliances plugged in. You trip a breaker, hopefully you then transfer load to another circuit. Breakers use two different methods to accomplish this, one uses a bimetallic strip and the current passes directly through, too high a current causes the strip to deflect. It acts on a mechanism much like the sear in a guns trigger, the deflection pulls the trigger causing a spring to open the contacts and turn off the circuit. Another type is thermal magnetic, current passing through the breaker causes a magnetic field to act on a coil tripping the breaker. When breakers are wired and work properly they prevent fires!

MaxineA+ They ground current.
Yes circuit breakers can help to prevent building fires. Circuit breakers will trip if an electrical current gets too hot, or if a current becomes overloaded. When a trip happens, the power is stopped to the electrical line, thus stopping the flow of power and the possibility of a fire.
A circuit breaker has a specific amperage trip setting. That is the number on the handle of the breaker. When an amperage that is drawn by a load goes higher than the setting on the breaker, the breaker will trip off. This tripping action opens the circuit and drops off the load that was causing a higher than normal amperage.

Why are fuse boxes or curcuit breakers good safety features in houses?
Fuse boxes or circuit breakers help prevent electrical fires by interrupting the flow of electricity when there is an overload or short circuit. This can protect the wiring in the house from overheating and causing a fire. Additionally, they make it easier to identify and address electrical issues, improving overall safety in the home.
When you add appliance to circuit you add what?
When you add an appliance to a circuit, you increase the electrical load on that circuit. It's important to ensure that the circuit can handle the additional load to prevent overloading and potential hazards like tripped breakers or fires. It may be necessary to add a new circuit or redistribute the appliances to balance the electrical load.

What safety device keeps electrical wires from overheating and prevent fires?
A circuit breaker is designed to protect electrical circuits from damage caused by overcurrents. When the current exceeds a safe level, the circuit breaker automatically interrupts the flow of electricity to prevent overheating and potential fires.
