What is the difference between elcb 30mA and elcb 300mA?
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.
What is difference between residual current circuit breaker and earth leakage circuit breaker?
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.
How connect the ELCB circuit?
we use to connect elcb using hands. with help of skrewdriver
How you check the elcb is working or not?
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.
Differetiate between solid earthing and ELCB?
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.

How do you make ELCB tester for testing ELCB for checking that ELCB is tripping after sensing say 30 mA fault current that is leakage 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.
Draw and explain the operation of fault voltage ELCB and residual current device?
ELCB means Earth Leakage Circuit Breaker -- it is used to trip the Circuit breaker if any leakage fault occured means

The very front of your tongue dectects what taste?
Sweet
What element can dectects bone diseases?
it came to india from africa
What is the difference between ELR and ELCB?
elcb is the daughter of ELR ,mcb is their one onlyn son
ELCB vs MCB?
Earth Leakage Circuit Breaker(ELCB) was given to a device that breaks the power supply when a fixed amount of current ,say 25-40 milli amperes flow through the earth line. The MCB (Miniature Circuit Breaker) is a device designed to protect a circuit's wiring from the serious damage which would be caused if it has to carry a current which is too high for the diameter of the its wire
What size ELCB do i install?
Normally 40 A /65A
What is a PIR system?
a pir sytem dectects heats and movement so basically like an alarm system!
How connect the ELCB circuit?
we use to connect elcb using hands. with help of skrewdriver
