A ground fault is a type of short circuit that occurs when the hot wire carrying current comes into contact with some grounded portion of the system, such as a bare copper ground wire, a grounded metal wall box, or a grounded portion of an appliance. As with the classic short circuit, a ground-fault causes resistance to instantly lessen, which allows a large amount of unimpeded current to flow …

A short circuit is a more serious reason for a breaker tripping. A "hard short" is caused when the hot wire (black) touches a neutral wire (white). In terms of the physics involved, a short circuit allows for a sudden unimpeded flow of electricity due to lowered resistance, and this sudden increase in current flow within the breaker causes the tripping mechanism to activate.

An Earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations with high Earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected.

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume …
