Why different electrical devices have different fuses and how the fuses are different?
The current flowing through a cable supplying a load or loads depends on the combined power of those loads, and the size of the cable is chosen according to the anticipated load. If the cable is overloaded, then it will draw excessive current (an 'overload current') and overheat, and its insulation may eventually fail, and present a fire hazard. If one or other of the load devices develops a fault, then that device may draw significantly more current (a 'short-circuit current') than it should and it will fail. So, cables are subject to over currents -i.e. 'overload currents' or 'short-circuit currents'.
A fuse is an over current protective device. It is designed to disconnect the cable supplying a load or loads in the event of an overload or short-circuit current occurring either in the cable or in the loads. By doing so, it protects the cable as well as the load, from overheating and prevents the possibility of a fire.
All fuses work on the same principle. A fuse carriercontains a fuse link, or fuse element, which is connected in series with the cable and its load. When an overload current occurs, the fuse link melts, and creates a break in the circuit, disconnecting the cable. The fuse link is carefully manufactured so that the larger the over current, the faster it melts.
Fuses are rated in amperes, according to the maximum current they can continuously carry without melting, and are manufactured in a range of standard current ratings. What makes each fuse rating different is the cross-sectional area of their fuse link; the greater the cross-sectional area, the higher the current rating.
In your home, individual circuits are each protected by a fuse*, sized according to the current capacity of the individual circuit. These, in turn are protected by a larger fuse which protects all the circuits. The larger fuse is designed to operate only if one of the individual circuit fuses fails to operate quickly enough. By fusing individual circuits in this way, an over current should only affect an individual circuit, without affecting any of the healthy circuits.
There are a great many different types and design of fuse, according to their application and the magnitude of system voltage they are to operate. Fuses designed to operate on low voltage systems are physically quite small, whereas fuses designed to operate of high-voltage systems are physically quite large -but they all work on the same principle.
*In residences, fuses are now being replaced by miniature circuit breakers (MCBs), which can be reset after they have operated, unlike fuses which must be replaced.
What else can I help you with?
Why do you have different sized fuses for different appliances?
because of fuses are good
The conductors in electrical devices are commonly made of?
Copper
What is a person who designs electronic devices called?
An electrical or electronic engineer.
What electrical devices was created in 1960's?
Some electrical devices that were created in the 1960s were the slim angle TV which featured a five inch speaker and 23 inch screen. The belt massager was an exercise machine made in the 1960s. A bed wetting alarm called Lite Alert Wee Alert was also created in the 1960s.
Who invented resisters?
Otis F. Boykin invented the electrical resistorand patented it on Feb. 21, 1961. He invented a total of 28 electronic devices
What should an adult do if electrical devices stop working in a home?
To start from basics... Fuses.
What should an adult do if if electrical devices stop working in a newer home?
To start from basics... Fuses.
What are electrical fuses?
Safety devices used in electrical circuits.AnswerA fuse is an overcurrent protection device, and will operate in the event of a sustained overload current or a short-circuit current.
What happens when Shirley goes down to change the fuses?
Shirley changes the blown fuses to restore power to the affected electrical systems. This allows for the proper functioning of devices and appliances that were previously not working due to the blown fuses.
What does the noncurrent-carrying wiring devices industry make?
Popular products include electrical conduits and fittings, boxes for outlets, switches, and fuses, and pole and transmission line devices
Are fuse used to detect electrical energy?
Fuses are overcurrent protection devices. If voltages get extreme they blow to save other components. So yes in a way they detect electrical energy.
What if your reading material mentions switches fuses and circuit breakers as three of the most important devices for?
cutting off or isolating an electrical circuit
What information can be found in an electrical panel diagram?
An electrical panel diagram provides information about the layout and connections of electrical components in a building or system. It includes details on circuit breakers, fuses, wires, and other devices, helping to identify and troubleshoot electrical issues.
What amps are the fuses?
Fuse SizesThe Amperage ratings [sizing] of fuses [and circuit breakers] is determined by the SIZE of the conductors [wires] in the circuit which they serve.The size of the wires is determined by the maximum expected current [measured in Amperes (Amps) or Milliamps (mA] needed by the electrical devices "fed" by the circuit.Therefore, the answer to your question is that there are many different "size" fuses which range in Amperage from thousandths of an Amp to hundreds of Amps.
Which fuses on 2006 Pontiac momtana for electrical power?
main electrical power fuses for 06 pontiac montana
Can electrical energy be transformed into many different types of energy by devices and components?
Yes.
What devices are used to protect people from an electric current?
Electrical devices such as circuit breakers, fuses, and ground fault circuit interrupters (GFCIs) are commonly used to protect people from electric currents. Additionally, electrical insulation, such as rubber gloves and mats, can prevent electric shocks in specific situations.
