fuses have a metal filiment that is designed to fail if the rated current is exceeded, circuit breakers use a electromagnet, the current from abrupt overloading or a short circuit will cause the mechanism to open the circuit, they also have a bi-metal mechanism which is more for a overload slightly above the breakers rating, if a load just over the rating persists the bimetal strip will open the circuit. there are also ground fault:gfci" and arc fault"afci" breakers. on top of a normal breakers duties, ground faults are generally used to protect from accidental electric shock in areas near water, arc fault breakers are relatively new and are designed to trip when there is a faulty switch, receptacle, cord, or appliance that could be a potential fire hazard
Fuses and circuit breakers do not protect a person from electrocution. They are in the circuit to protect the feeder conductors from having over current applied to them. The only type of breaker that will protect you from getting a shock is a GFCI.The way that fuses and breakers stop household fires is by opening the fault current on the circuit before the fault temperature can rise high enough to ignite any surrounding combustible materials.
Fuses or circuit breakers are termed 'overcurrent protection devices', which protect circuits from either an overload current or a short-circuit current.

You do not build a series circuit in your home. The only series circuits are the circuits that go through circuit breakers, light switches, and relays. Electrical and electronic devices use internal series circuits but those are the only ones people build. No one builds series circuits for house wiring. Electrical outlets are connected with parallel wiring.
A fuse is a device used to keep electrical circuits from overheating is not a true statement. A fuse is used to protect the wire of the circuit from an over current being applied to the circuit. This over current could be caused by a couple of scenarios. Two non insulated conductors touching one another and creating a short circuit. Another cause could be an non insulated conductor touching adjacent grounded equipment. Whatever the cause the fuse will isolate the fault instantaneously.
Both of these devices are safety devices used to open a faulted circuit and stop the current flow.
Fuses and circuit breakers are used to protect the wiring and devices from overload and heating caused by short circuits, short circuits that, if unprotected, could cause major damage and/or fire due to excessive current.

They protect the downstream components from spikes in the eletrical system.CommentFuses and circuit breakers do not protect against 'spikes', which are near-instantaneous voltage increases. Fuses and circuit breakers are overcurrent protection devices, which protect appliances against excessive current due to overloads or short circuits. CommentFuses and circuit breakers are used to protect the wire feeder that supplies the load. A load could be connected to a circuit that would cause an increase of amperage above what the wire is rated for. If this condition happens the fuse or circuit breaker will open the load from the supply service.
It is usually classed as a device that will open the circuit if the current in the circuit goes high. Two examples of these types of devices are fuses and circuit breakers.
Yes, in the form of GFCI circuit breakers, not as a receptacle.
Each device has its own special use. Glass fuses can protect circuit at very low amperages. They are usually used to protect printed circuit boards and control panel circuits. Breakers protect circuits from short circuits and overloads. These devices are used in service distribution panels to protect the wires that feed the loads. Circuit breakers can be from 15 amps up into the thousands of amps.
You do not build a series circuit in your home. The only series circuits are the circuits that go through circuit breakers, light switches, and relays. Electrical and electronic devices use internal series circuits but those are the only ones people build. No one builds series circuits for house wiring. Electrical outlets are connected with parallel wiring.
Circuit breakers do the same thing as fuses. They interrupt current flow when a certain preset point is reached. The difference between circuit breakers and fuses are that circuit breakers are resettable and reusable, whereas fuses are one time devices that must be replaced after they blow.
Circuit breakers and fuses are both devices that protect an electric network byautomatically opening a circuit when the current exceeds a predetermined level.
The GSR plug is the newest device to perform this function. It becomes a mini circuit breaker for the circuit and is critical for high risk areas such as kitchens and bathrooms.The basic circuit breaker is another device. It opens the circuit when the amperage exceeds the rating of the breaker. It is a device that can be reset.The electrical fuse is the eldest of the devices. The disadvantage is that it must be replaced when the circuit is opened by overload.Circuit breakers and their cheap alternative, fuses, are used to disconnect the power if an excessive current flows.
Yes, the total current delivered to multiple devices in parallel is the sum of the individual branch currents (the vector sum if there is inductive load). Circuit breakers are resettable automatic switches that help protect against circuit overload (such as running too many hair driers and heaters on at one time) and faults (such as dropping the hair drier into a bathtub). Circuit breakers "operate" (or open) to stop current flow to the fault or overloaded circuit.
