	Circuit breaker - Wikipedia, the free encyclopedia
		Circuit breakers are made in varying sizes, from small devices which protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
		The circuit breaker's contacts are held closed by a latch and, as the current in the solenoid increases, the solenoid's pull releases the latch which then allows the contacts to open by spring action.
		Circuit breakers for larger currents are usually arranged with pilot devices to sense a fault current and to operate the trip opening mechanism.

	Earth leakage circuit breaker - Wikipedia, the free encyclopedia
		The term Earth leakage circuit breaker (ELCB) is often incorrectly used to describe its modern counterpart the Residual-current device (RCD).
		An earth leakage circuit breaker (ELCB) is a device with two earth terminals used to directly detect currents leaking to earth from an installation and cut the power.
		They were mainly used on TT earthing systems before RCDs became common.

	CBI -- Technology: Ground Fault Protection
		CBI Earth Leakage Protection Devices are the core balance type which monitor the difference in the current flowing in the live and neutral conductors.
		CBI earth leakage units are manufactured to operate in the tolerance band of 19 to 26 mA.
		These earth leakage units from 100 to 375 mA provide reasonable protection from the risk of electrical fires, but it should be noted that under certain circumstances a current of less than 500 mA flowing in a high resistance path is sufficient to bring metallic parts to incandescence and start a fire.

	circuit breaker
		Circuit breakers usually work by means of magnetic-type relays or solenoids.
		When a current exceeds a fixed limit as it flows through the magnetic coil of a circuit breaker, a triggering mechanism is released, pulling the contacts apart and opening the circuit, thus preventing any more current flowing.
		Circuit breakers have many advantages; for example, they are fast acting, can be adjusted to operate at different current values, and can be easily reset.

		The earth wire in a three wire mains supply is to conduct away any small leakage currents, and also to provide a low resistance path to earth from the case of instrument and cause a fuse to blow if a short circuit should occur inside the equipment.
		The ELCB monitors the current flowing to earth, usually by measuring the difference between the currents flowing in the live and neutral wires.
		Since the leakage current is not measured in the earth wire the same principle can be applied to a two-wire supply to a double insulated device.

		Electric devices that are connected to disconnection transformers are automatically being disconnected from their grounding connection in the case of an internal insulation breakdown so that no return flow of electric current through the human body to the earth can occur anymore.
		If the parts of an electric device or machine that do not conduct current are connected to protective grounding through a ground electrode then in case of an accident the fuse of the circuit interrupts the current flow.

		Ground-fault circuit interrupters (GFCIs), also called earth leakage or residual-current circuit breakers, can sense leakage current to earth ground from live parts and interrupt the circuit automatically when leakage current exceeds a predetermined value.
		The term earth-leakage circuit breaker (ELCB) is sometimes used interchangeably with GFCI, though strictly speaking an ELCB is a different type of device.
		ELCBs are generally used only with what are called TT earthing systems, where the earth connection protecting the consumer is through a local connection to earth (often near the receptacle), independent of any earth connection at the generator.
