Want this question answered?
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.
Time Tripping was created in 1983.
elcb is the daughter of ELR ,mcb is their one onlyn son
tripping tripping tripping,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
Normally 40 A /65A
we use to connect elcb using hands. with help of skrewdriver
What to do while tripping
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.
Inverse Definite Minimum Time Lag = IDMT relay It's a electromagnetic type rotating disk relay. Tripping time of relay decreases with increasing fault current. see http://myweb.tiscali.co.uk/robert.booth/uni/docs/Power%20Supply%20Assignment%203.pdf
