An ELCB is an Earth Leakage Circuit Breaker and is a device used for safety purposes to detect stray voltage or current on a metal enclosure in order to prevent shock. The two types of ELCB are Voltage-operated and current-sensing protection. The difference between a 30mA ELCD and a 300mA ELCB is that the 30mA version will have a much higher level of sensitivity, tripping the device is a much lower current.
we use to connect elcb using hands. with help of skrewdriver
By simulating a earth leak on the device connected to ELCB. A short between phase and the body or earth point. Care must be taken. It must be done by a trained Electrician only. It is dangerous to do it.
Voltage-ELCBs were first introduced about sixty years ago and Current-ELCB was first introduced about forty years ago. For many years, the voltage operated ELCB and the differential current operated ELCB were both referred to as ELCBs because it was a simpler name to remember. But the use of a common name for two different devices gave rise to considerable confusion in the electrical industry.
ELCB is the connection to the direct earth path using protective device.while solid earthing is without protective device.A form of ELCB should be installed when direct earth path of low enough impendance can not be obtained.
Normally 40 A /65A
elcb is the daughter of ELR ,mcb is their one onlyn son

Take a wire and ground the neutral at the load point. Some current will leak through ground and the same will be sensed by elcb and trip. Other method is simply test a lamp across phase and earth with out using neutral.elcb should trip if it is functioning correctly.

Should be E1cB.https://en.wikipedia.org/wiki/E1cB-elimination_reaction
ELCB means Earth Leakage Circuit Breaker -- it is used to trip the Circuit breaker if any leakage fault occured means

The first definition, by the electrical code, covers it perfectly.
An ELCB (Earth Leakage Circuit Breaker) distribution box is a type of electrical box that is used for electrical GFCI (Ground Fault Circuit Interrupter) outlets. This is the type of outlet that requires a three-prong plug in, one wire of which is grounded. GFCI outlets are set up so that if there is a circuit overload, the outlet is shut off until it is reset, manually.
