Cost. It is because of the ease of resetting a breaker after a fault trip. A fuse is a throw away device after it trips.
The size and composition of fuse wire is designed to "burn through" in an over current situation. That works fine as long as the current is lower than the fused rating. If you were to use the wire in the circuit then all your wire would essentially disintegrate in an over current situation.
That will draw about 9 amps at 120V. A 15 amp breaker if the circuit conductor is #14 or 20 amp breaker if the circuit conductor is #12. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
I believe that the wires supplying a 30 amp circuit must be at least 10 gauge. If you have 14 or 12 gauge wires going to or from your 15 amp breaker, then drawing 30 amps over it could cause a fire hazard. It's like using those cheapo non-UL certified extension cords to plug a MILLION X-mas lights into (drawing more power than the wires can handle). You also have to make sure this GFI outlet you refered to is rated for 30 amps. Do not simply swap out breakers. Overloading the wires in the circuit protected by that breaker will cause a fire. If you need a 30 amp circuit you must run #10 gauge wire.
In the USA, a National Electrical Code specifies things like circuit breaker sizes. The purpose of the circuit breaker is to protect the wiring (which is usually in a metal or plastic conduit, or in its own plastic insulation, and also is usually hidden in the wall, ceiling, or floor). The size of the circuit breaker (such as 15-amp, 20-amp, 30-amp) depends upon the size of the wiring. Wire guage sizes (in USA) are typically 14 awg (for lighting and light-duty circuits up to 15 amps), 12 awg (bigger than 14 awg, for power outlets as well as lighting circuits up to 20 amps), and larger sizes for special purposes. Most modern kitchens have two or more 12 awg circuits for the purpose of providing power to appliances such as toasters, mixers, etc. A 20-amp circuit breaker would protect a 12 awg wiring system designed to carry 120 Volts and 20 amps (amperes). For safety, you must determine the size of the wiring in order to decide which size circuit breaker will protect it. 15-amp circuit breaker for 14 awg wiring (which is easy to bend with finger tips) 20-amp circuit breaker for 12 awg wiring (which is hard to bend with finger tips) 30-amp circuit breaker for 10 awg wiring (which is very hard to bend with finger tips) The appliances and other items that you plug into an electrical outlet rely upon their own fuses or other design features for protection. The circuit breaker protects the wiring to prevent fire. This is IMPORTANT. Do not use a larger circuit breaker than the wiring can safely handle. AWG = American Wire Guage Smaller numbers are for bigger wires. 6-awg is about as big as a wooden pencil. 30-awg is about as fine as a human hair. I would add this: do yourself a favor, make 12 gauge wire your standard when putting in any new wiring (unless you are going higher than 20 amp circuit) . Don't mess with 14 gauge at all. The cost difference is peanuts.
A buzzer works in an electric circuit by creating vibrations in a diaphragm when an electric current passes through a coil. The vibrations produce sound waves that we hear as a buzzing noise. By controlling the flow of current through the coil, the buzzer can produce different tones or patterns of sound.
Circuit breakers do not use anything, they are a controlling device. They can automatically open the circuit if the current exceeds the current rating and you can manually disconnect the power from the circuit.
Circuit breakers which are basically an automatic off switch if the current goes over the amps listed on the face of the breaker. The breaker will simply "trip" or turn off if you have a power surge that exceeds the amps. They do not burn out like fuses do, so you generally do not have to replace them if they are tripped. Simply fix the cause of the surge and flip the breaker back on.
yes SF6 gas is used in modern ckt. breaker.

In most appliances the single thing that prevents an overload is the fuse. In modern electronics there are various devices that can be used for power management which can limit the current drawn by reducing the load voltage. see: http://en.wikipedia.org/wiki/Current_limiting
Most modern Premier electric stoves do not use fuses; instead, they typically rely on circuit breakers for protection. However, some older models may have fuses as part of their electrical system. If you're experiencing issues with your stove, it's best to consult the user manual or a professional technician for guidance on troubleshooting.
The main difference between a fuse box and a breaker box is the way they protect electrical circuits. A fuse box uses fuses that need to be replaced when they blow, while a breaker box uses circuit breakers that can be reset. Breaker boxes are more commonly used in modern electrical systems because they are safer, more convenient, and provide better protection against electrical overloads.

Both devices are safety measures for the electrical circuit. The home fuse is a glass affair with a burnable core. If the core melts, the circuit opens. The circuit breaker does the same thing, but is a "reset" device, meaning that it can be used over and over again. The fuse is replaceable, but not "reset-able." Both systems are used in modern homes, but the fuse system is being replaced by the circuit breaker system.
A switch is installed in a circuit to stop the current flow. Without the switch there is no way to disconnect the operation of the circuit's load. In modern households the switch is a convenient way to control room lighting from a convenient location. Without switches the circuit power would have to be controlled from the service distribution panel's breakers. In this scenario the breaker would be in the same class as a switch.
Practically all electrical devices include integrated circuits today. Anything from a domestic electric kettle to a space station will include them
