Safety Fuses in interior and a motor compartment

Safety Fuses in interior and a motor compartment

In car Fiesta safety fuse are used for protection of electric circuits against overloads and short circuits. If additional consumers of the electric power are connected to an electric circuit or because of malfunction there is a short circuit (that represents not that other as excessively increased course of a current), the electric circuit is overloaded. If the current exceeds the certain admissible size, safety fuses simply interrupt current of a current. Thus they interfere with occurrence of damages to the car, for example ignition of wires. In car Fiesta flat safety fuses in which in case of an overload the fusible string fuses are installed. The safety fuse carries out the function and in that case when already completely loaded electric networks are overloaded with additional consumers, for example, modern musical installations, speaker and is inadmissible powerful lamps. Vacuum cleaners and refrigerators which you include in lighter, can sometimes serve as the reason burnout the fuse. In case of need equip the car with a separate electric network for the additional electric equipment and, accordingly, install the fuse. To exclude possible unpleasant consequences, address to the automobile electrician who will lay necessary wires (section not less than 1,5 мм2) and will instal a necessary safety fuse.

Protection of various electric circuits
That your car at malfunction in an electric equipment has not remained completely without the electric power, engineers of company Ford have allocated consumers on various electric circuits. Management of the engine and the majority of powerful units have the electric circuit. Minor consumers of the electric power are collected in various electric circuits, each of which is protected by the fuse. The circuits connecting a starter, the storage battery, the generator and the switch of ignition are not protected by safety fuses only: here constantly there is a full voltage of the storage battery.

WARNING
Observe extra care at work with electric circuits: first always disconnect wires from plugs of the storage battery! Otherwise serious damages and ignitions of wires down to a fire in the car are inevitable.

THE TECHNICAL DICTIONARY
The safety fuses used in car Fiesta
In holders of safety fuses are inserted so-called flat safety fuses. In the transparent plastic case fuse out two flat contacts connected among themselves by a fusible conductor. You find out fused fuse on the broken off fusible conductor. Often underside of the plastic case happens damaged or melted off.
Color of safety fuses
From a underside of each safety fuse value of force of a current (A) is specified. Color of a safety fuse also meets to value of a protected current.
