Yes, there is danger when an electrical circuit is unfused. The purpose of a fuse [or circuit breaker] is to protect the conductors [wires] in an electrical circuit from excessive current [measured in Amps] from flowing through the circuit. Excessive current flow [more Amps than the conductor is capable of carrying] causes heat to be generated within the wire. If the excess current is great enough for enough time, then the build-up of heat can damage the insulation on the wire, possibly causing a short circuit between the "hot" wire and another wire [or metal body part] which is "grounded" [connected to the vehicle frame and thus to the battery negative [ground] terminal. A direct short of that nature can cause so much heat, and possibly arcing and sparking that a very dangerous fire can be started. Such a fire will do much damage to the electrical system and other parts of the vehicle, and could result in personal injury, even death. Therefore, a properly sized fuse should be used in all electrical circuits.

Why does fuse blow in Cadillac?
Fuses blow, in any application, when the current in the circuit exceeds the limit preset by the fuse selection. It is also possible, if the fuse terminals are corroded, for heat to be generated, causing the fuse to melt, giving the appearance of having blown.
Can a 3.15A 250v fuse be replaced with a 5A 250v fuse?
NO! The circuit wiring is protected by that 3.15 amp fuse. Put a 5 amp fuse in the circuit and the wiring may overheat and cause a fire. Never over-fuse any circuit even in an emergency.
What happen if fuse is connected to neutral wire?
The fuse will be blown off in case of any fault. But the circuit will not be isolated because of the presence of fuse in nutral line. current will still flow and the line will be so dangerous.
Is there any alternative for fuse in house wiring system?
Yes. Circuit Breakers.
Does electric dryer get damaged by short circuit in socket?
The fuse is there to disconnect the supply when there is a short circuit, before any damage is done.
Does the power windows in a Chrysler LeBaron GTC 1989 require a fuse?
YES! Everything that is electrical in nature on any vehicle is protected by a fuse, a fusible link or a circuit breaker. Find your fuse panel and each fuse should be labeled as to what circuit it protects. Be sure to replace any fuse that burns out with one of the same amperage. If the fuse keeps burning out it is doing what it was designed to do--protecting against overheating and a possible fire. If the fuse keeps burning out there is a short in that circuit that needs to be located and repaired as soon as possible.
What do you think would happen if you put a 3A fuse in a plug used for kettle?
I know what would happen. The three amp fuse would blow. Any device that is plugged into a receptacle with out having sufficient resistance to limit the current flow will dead short the circuit and cause the breaker that feeds the circuit to trip. In this case the fuse being of a lower rating that the feed breaker the fuse will blow without tripping the receptacle's feed breaker.
How does closed circuit work?
A closed circuit works by having electricity flow in a complete circuit or circle or any closed shape.
What will be happen if you use earthing in place of neutral in any circuit?
* * * DANGER * * * DANGER * * * DANGER * * *Do not, under any circumstances, use earth ground instead of neutral in a circuit. Besides being a violation of the US National Electrical Code, and probably the applicable electrical code for any country that has an existing neutral system in place, it constitutes a hazard because the earth ground conductor is not rated to carry operational current. It is only there to carry momentary fault current so as to trip the protective device (fuse or circuit breaker) in the distribution panel. Also, placing operational current on protective earth ground can raise the voltage on that conductor, creating the potential for an electrocution hazard.
What is the weakest link in an electric circuit a switch a receptacle the pilot lamp or the fuse?
The fuse, because it is expected to fail first on any fault.
What is fuse used for?
For protection in an electrical circuit, for de-initiating an explosion or combustion of any sort.
What would have caused your 40 amp fuse to blow?
What Causes Any Fuse to "Blow?"The cause is what fuses were invented and are used for:to detect and protect against SHORT CIRCUIT conditions, and /or CIRCUIT OVERLOAD conditions.
