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.
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.
Normally 40 A /65A
we use to connect elcb using hands. with help of skrewdriver
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
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.
