The purpose of a circuit breaker is to open the circuit in the event of an overload. Wires/conductors are only rated for a specific Amperage. If this amperage is exceeded the conductor/wire begins to heat up and given enough time it becomes a fire hazard.
For instance a 15 amp breaker will trip once the Amps drawn through that circuit exceed 15 amps.
The short answer is to keep you safe.

∙ 8y agoThe function of a breaker is two fold. It has the ability to open an electrical circuit when the load current of the circuit becomes higher that the rating of the breaker. This is referred to as an overload trip. The other feature of a breaker is that it will open the circuit instantaneously on a short circuit condition. This is referred to as a short circuit trip.

What is the function of the fuse or circuit breaker in a circuit?
A circuit breaker/fuse is designed to protect the wiring from getting overloaded.
Will a circuit breaker function properly if it is back fed?
Yes. The circuit breaker "does not care" which direction the current comes from. It is capable of protecting the circuit in any case.
What is the function of an LBB relay?
A local breaker backup relay is used to check the operation of distribution circuit breakers and to trip the feeder circuit breaker if the distribution circuit breaker fails to trip on an overload.
What is function of vcb?
VCB is Vacuum Circuit Breaker. It is one of the type of Circuit breaker. In VCB arching chamber is vacuum instead of oil or such arc quenching media. Its function is to break the circuit automatically in case of fault or to isolate the circuit under normal situation also.
What are the function of consumer box?
what is a circuit breaker / fuse current rate value for lamp and fan load circuit
What is the function of a 15 amp circuit breaker?
To trip when current is in excess of 15 amps and protect the circuit components.
The Function Of A Twenty Amp Breaker?
It limits the current to the circuit at 20 Amps. If a load on the circuit draws more than 20 Amps the breaker will trip and interrupt the current to all devices on the circuit.
Will a circuit breaker function the same if supply and loads are reversed?
Yes, a circuit breaker will function the same if supply and loads are reversed. This is the way that some sub panels are fed instead of a main disconnect at the top of the distribution panel.
How the circuit breaker differ in its function from combination switch fuse unit?
The function is the same in that they both are designed to remove an over current situation by opening the circuit. A tripped breaker can just be reset. A blown fuse needs to be replaced.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
Is the circuit where is the is the circuit where is the circuit breaker for the?
The circuit breaker for the headlights is intergrated with the headlight switch.
What would happen if a 240V breaker was on and someone attempted to turn on the clothes dryer?
Don't understand this question. If the breaker is on, then the dryer would function normally, if the breaker your are referring to is the one for the dryer. If the breaker is off then no function. A dryer runs on 220.
