An electric fuse is a device that an interrupt the flow of electric current when it is overloaded. This implies, it is basically a short piece of conducting material that allows only required amount of current to flow through it thereby saving the expensive electrical appliances from burning out.

The basic function of an electric fuse is to prevent healthy part of the circuit from being damaged and to limit the damage to the faulty sections or items to the lowest possible level.

The current is interrupted when the elements which carry the current are melted by the heat generated by the current. When a condition of overload arrives, fuse blows off. This confirms the replacement of a new fuse so as to further protect the devices from any damage.

Replacing a fuse is a pretty easy home maintenance task but you need to be very careful because electricity can be dangerous. Unplug all the devices that are connected to the power supply prior to fuse replacement. In addition to this, use a correct rating fuse every time you replace it.

Accomplish the task with proper safety measures. Wearing a good quality insulated gloves would be safe enough. Use proper tools to handle the fuse wires and terminals and avoid touching the metal parts with bare hands.

Again and again blowing of the fuse even though no device is turned on indicates serious faults in the wiring. Therefore, its a time to in an electrician before the situation worsen.

Fuse being very reliable and cost effective devices are commonly used in automobiles. For some applications, fuses still provide the best method to protection. Very compact fuses limit overloads to a single circuit and minimize fire danger. High breaking capacity and good power quality are some other advantages of electrical fuse.

Fuses are employed in almost every electrical appliance so as to protect them against overload damages. Some very common areas of application of electrical fuse are motor bikes, ships and other vehicles. Moreover, fuses can provide for redundancy for the purpose of preventing reduction of yield of the semiconductor devices.
