Overload

An electric overload occurs when too much current passes through electric wires. The wires heat and can melt, with the risk of starting a fire. For Example : In building the wires meant for light and fans can carry a certain amount of current safely. i.e. with overheating. If we connect a number of devices like lamps and heaters to the . . .

Risk of overload: things to avoid

Putting too much pressure on a water hose can make it burst. The principle is similar for electric wires: if too great a current flow is required by several items of equipment connected to the same line, this produces overload. Avoid therefore as far as possible: plugging several power-hungry items of equipment into the same socket using a m . . .

Relation of Short circuit with overload

A short circuit is a direct low resistance connection between two pointes across which there is a voltage. Due to overload (too much current flow) occurs short circuit. A short circuit is simply a low resistance connection between the two conductors supplying electrical power to any circuit. This results in excessive current flow in the power source . . .

Fuse

A fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit including the source of power and the load. Its essential component is a metal wire or strip that melts when too much current flows through it Electric fuse is a protective device which protects electrical equipment in th . . .

Construction of Fuse

The fuse wire is made of zinc, copper, silver, aluminum, or alloys to provide stable and predictable characteristics. Fuse should be of low resistance and low melting point as per the requirement current rating for overcurrent protection. . . .
