FUSES AND CIRCUIT BREAKERS;
FUSE;
The most common type of fuse is made up of a metal wire or filament that is enclosed in a glass or ceramic and metal casing.The fuse is typically plugged into a central fuse box where all the wiring passes through. When the electricity is flowing normally, the fuse permits the power to pass unobstructed across its filament, between circuits. If an overload occurs(when current is more than normal), the filament melts, stopping the flow of electricity.so fuse saves saves use from electrical shocks and also saves our devices from burning.
CIRCUIT BREAKERS;
A circuit breaker works in a different way as compared to a fuse.It has an electromagnet (or solenoid) or a bi-metal strip. when turned on, the breaker allows electrical current to pass from a bottom to an upper terminal across the solenoid or strip. When the current reaches unsafe levels, the magnetic force of the solenoid becomes so strong that a metal lever within the switch mechanism is thrown, and the current is broken.
GROUND FAULT CIRCUIT INTERRUPTS;
Ground fault interrupters are designed to protect from electrical shock by interrupting a household circuit when there is a difference in the currents in the "hot"wire or live and neutral wire. Such a difference indicates that an abnormal diversion of current from the "hot" wire is occuring. Such a current might be flowing in the ground wire, such as a leakage current from a motor or from capacitors. More importantly, that current diversion may be occuring because a person has come into contact with the "hot" wire and is being shocked. When a circuit is functioning normally, all the return current from an appliance flows through the neutral wire, so the presence of a difference between "hot" and neutral currents represents a malfunction which in some circumstances could produce a dangerous or even lethal shock hazard.
