What is the difference between ELR and ELCB?
elcb is the daughter of ELR ,mcb is their one onlyn son
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
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 is the name of a safety device that will shut off flow of electricity?
Devices used to open an electrical circuit are called OCPD's. (overcurrent protection devices) The most common are circuit breakers and fuses. In commercial motor starters they often employ another OCPD called a "heater" (UK thermal fuse) which is a metal strip which melts like the element in a small fuse when too much current (amps) go through it. They devices are in the circuit primarily to protect the wiring and devices they power. Circuit breakers such as in your home panel do protect you from a "shorted" circuit. Another safety and most common in residences are GFCI's or ground fault circuit interrupters (UK ELCB, Earth Leakage Circuit Breaker or RCD, Residual Current Detector) which come as both a receptacle (female plug) or as a circuit breaker.
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.

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.
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 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?
To make an ELCB tester for testing if the ELCB is tripping at 30 mA fault current, you can use a variable power supply to simulate the fault current. Connect the ELCB to the power supply through a resistor to limit the current to 30 mA. Apply the current to the ELCB and check if it trips properly. Ensure you have the necessary safety precautions in place when working with electrical circuits.
What size ELCB do i install?
Normally 40 A /65A
How connect the ELCB circuit?
we use to connect elcb using hands. with help of skrewdriver
What is ElcB reaction?
Should be E1cB.https://en.wikipedia.org/wiki/E1cB-elimination_reaction

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.
What is ELCB full form?
E a r t h l e a k a g e c i r c u i t b r e a k e r ( e l c b )
Which of the following definitions describes a circuit breaker ground fault circuit interrupter?
The first definition, by the electrical code, covers it perfectly.
