1.)A SHORT CIRCUIT
-allows a charge to flow along a different path from the one intended. In electrical devices,unintentional short circuits are usually caused when a wire's insulation breaks down, or when another conducting material is introduced,allowing charge to flow along the different path than the one that is intended.
2.) FUSE
2.) FUSE
-is short for "fusible link", is a type of over current protection device who's essential component is a metal wire or strip that melts when too much current flows. When the fuse element blows, the indicating pin extends to activate the micro switch or relay which in turn triggers an event.
3.)Circuit breaker
3.)Circuit breaker
-is an absolutely essential device in the modern world, and one of the most important safety mechanisms in your home. Whenever electrical wiring in a building has too much current flowing through it, these simple machines cut the power until somebody can fix the problem. Without circuit breakers (or the alternative, fuses), household electricity would be impractical because of the potential for fires and other mayhem resulting from simple wiring problems and equipment failures.
4.)Electrical Overload
4.)Electrical Overload
-is a situation where the wiring to or within a machine or system is subjected toa greater electric current load than it was designed to carry, leading to excessive heating of the wires and a possibility of fire.
5.)This excessive current load can be a result of electrical insulation failure ( a short circuit) or human error. A correctly designed electrical system incorporates suitable overload protection devices to prevent damage should such a situation occur. Fuses and circuit breakers are most commonly employed for this purpose.
6.)Short Circuits are likely to result on a very high current flowing and therefore quickly trigger an over current protection device.Overload wires can also overheat,sometimes causing damage to the wire's insulation,or a fire.
