Fuses are available in any car and in many models of electrical engineering, because if a short circuit or overload occurs in the electrical network, the equipment may well fail.
Main function of fuses
Their main function is to open the electrical circuit, in cases where the current strength in it exceeds all permissible values.
This means that fuses are able to provide effective protection for both electrical equipment and wiring.
If they are used, the risk of fire and short circuit is reduced to zero.
And the main advantage of fuses is that they cost a penny, but protect expensive equipment.
If the fuse fails, then its replacement is in no way associated with serious financial investments and installation difficulties.
True, you need to change a blown fuse to its nominal counterpart. For its defining characteristic is the strength of the current.
When the fuse is triggered, it becomes unusable, that is, it turns out that it takes over the entire electric shock that has arisen in the network.
There are more powerful fuses, the action of which does not apply to a separate electrical appliance or a small electrical network.

And for one or more rooms, or even an apartment.
The strength of the current and its effect on the operation of the fuse
In cases where the current strength has an effective value that exceeds the allowable value, the fuse works one hundred percent.
And in the circuit of each individual equipment, a personal fuse is installed, which has the appropriate rating.
When a fusible insert, designed for a lower current strength, is installed in an electrical circuit, it is able to operate even at a reduced current strength.
Of course, such a fuse can provide protection to other devices, but it will only need to be changed more often.
And when a fusible insert is installed, designed for a higher current strength, no one will guarantee that the current passing through the circuit may be higher than allowed for devices.
This means that these devices will simply burn out, and the fuse will not do its job.
Fuse replacement specifics
To replace the insert with a fuse, you must first find out the cause of its burnout.
Usually, such an unpleasant phenomenon is observed when the integrity of the wires is violated or as a result of equipment failure.
In case of malfunctions of the generator and electrical networks, blown fuses are also possible.
It is very simple to determine which fuse has blown, even without special devices: if there is a suspicion that a particular fuse has blown, you just need to remove it from the socket, and put, for example, a screwdriver in its place.
How not to do.
Equipment turned on in advance must be turned off in an arbitrary sequence.
If during the shutdown process a spark appears between the sockets, this will indicate which device has become unusable.
But do not forget that the screwdriver must have an insulating handle, and you must have dielectric gloves on your hands.
