Electrical circuits use fuses to prevent electrical overload to the circuit, and possible electrical fires stemming from the overloaded circuit. A household electrical system can be compared to your home's Plumbing. Just as water is pressurized coming from a city's water supply, so is the electricity coming from your local utility provider. The pressure of current is "voltage." The current carrying capacity of electrical wires is "amperage." Just as larger wires can handle a greater capacity of water, so may larger guage/diameter wires handle greater voltage. When you go to your local hardware store, you buy wire based on its amperage. Your home is specifically wired according to the placement of appliances or items that use electricity. For example, the outlet behind your refrigerator is most likely a 20 to 30 amp circuit, as the refrigerator demands a greater volume of electricity to keep the items inside it cool. Whereas, the outlet in your bedroom may only be a 15 amp circuit, as the items you plug into it may be a lamp or clock radio, which do not demand as much electricity as a refrigerator. All the electrical circuits in a home begin at a fuse box. The city's power supply is routed into your home's fuse box. In the fuse box, the electricity is distributed to all the electrical circuits in your home. At the beginning of each circuit is a fuse or circuit breaker. The amperage of a fuse or circuit breaker is based upon the demand of power each circuit must serve. The fuse for the circuit that powers your refrigerator is of a greater amperage than the circuit that powers the lamp next to your bed. Inside each fuse is metal element that melts when the circuit is overloaded and gets too hot. The element in a 15 amp fuse melts at lower amperage than would the element in a 30 amp fuse. If you attempted to plug your kitchen's refrigerator into the outlet in your bedroom, the circuit would get too hot, and back at the fuse box, the element in the fuse at the beginning of that circuit would melt or "blow". This essentially breaks the circuit, stops the flow of electricity, keeps the wires in that circuit from overheating, and helps to prevent electrical fires by doing so. Many homes today use circuit breakers in lieu of fuses. The circuit breaker is a spring loaded switch that turns itself off when a circuit becomes overloaded, or gets too hot. I hope that answered your question.

A circuit breaker is used in many homes instead of a?

fuse. It is a safety device that automatically switches off the electrical circuit when it detects an overload, preventing overheating and potential fires. Circuit breakers can be easily reset after they trip, unlike fuses that need to be replaced.


What is a fuse in an electrical appliance?

A fuse is a safety device that protects electrical appliances from overcurrent or short circuits. It is designed to melt and break the circuit if the current exceeds a safe level, preventing damage to the appliance or a potential fire hazard. Fuses need to be replaced once they have blown to restore the electrical circuit.


What is discrimination factor of electrical circuit protection?

Electrical discrimination is to do with selecting the correct protection in the fault path of an electrical circuit. To illustrate, if you have a machine at the end of an electircal circuit and that is protected by a 13A fuse lets say, and then you have a 20A circuit breaker protecting that at the consumer unit (fuse board), and then the main switch on the consumer unit is a 10A circuit breaker, then every time the machine uses more than 10A of power the main switch will trip and disconnect everything connected to it, that is where discrimination is not achieved. Basically it is where the circuit protection closest to the macine is smaller and it gets bigger as it goes boack to the source, then discimination is achieved. I hope that helps. If not then it probably need a drawing to help answer.


What kind of fuse need to use for 240V outlet?

For a 240V outlet, you should use a fuse that is rated for 240V. The fuse's amperage rating should match the amp rating of the circuit and be appropriate for the connected devices. It's important to use the correct type and rating of fuse to protect the circuit from overloading and electrical hazards.


What is a fuse panel?

a place where all the fuses are located together. In the house this is where the power is controlled to the lights in the house ect, and can be switched on/off independent of other areas of the house if that's what you want to do and if it is possible with your fuse panel/board. A fuse panel contains electrical fuses or circuit breakders in a central location in a building, vehicle, etc.


Why does the fuse keep blowing in your cub cadet garden tractor?

There's a few reasons and some things you need to check. What electrical circuit is the fuse protecting to start with? Is there electrical wires coming to and from the fuse? If so, the most common problem is that a live wire has worn through it's insulation by rubbing against a peice of steel and causing a direct path to ground, a spark, which overloads the fuse and blows it. Also check to see if the fuse is the wrong amperage size for the circuit.


How does an open circuit occur?

An open circuit does not work. You need to have a complete circuit for the electrical current to flow back to its source. For example: An open circuit occurs when a series fuse blows or a connector is unplugged.


Will a blown fuse cause the wipers not to work?

Only if the fuse protects the circuit that the wipers are on. If replacing the fuse does not solve the problem, check the replacement fuse; if it has also blown then you have a short circuit on that circuit and need to consult an auto electrician


Does a fridge need a dedicated circuit for proper electrical operation?

Yes, a fridge typically requires a dedicated circuit to ensure proper electrical operation and prevent overloading the circuit.


What things need a electrical circuit?

Many common household appliances and devices require an electrical circuit to function, such as light bulbs, computers, refrigerators, televisions, and heating systems. Additionally, electronic devices like smartphones, tablets, and gaming consoles also rely on electrical circuits to operate.


How do you fix a blown fuse?

You can easily replace it but you need to know why it blew in the first place. All fuses are marked on the fuse box or in the drivers manual as to which circuit they protect. Determine which circuit that blown fuse protects and inspect that circuit for troubles.


How do circuit breaker keep the wires in a electrical circuit from overheating?

A circuit breaker is designed to 'break' in a circuit if a short circuit (or other malfunction) occurs. This prevents overheating (or burn-out) of the circuit wires. In older systems, you would need to find which fuse wire has fused and replace it. In a circuit breaker, once the fault has been found and corrected, the breaker is simply switched back on.
