To test your ELCBs, you only need to ensure that it is in the ‘ON, position.
However, before you begin testing your Eearth Leakage Circuit Breakers (ELCBs), secure that your device’s wirings are properly connected to their terminals.
For optimal safety, we recommend that you seek professional assistance in installing or testing your ELCBs at home.
To test your ELCBs, simply make sure that the device is in an ‘ON’ setting.
Then, press the ‘TEST’ button to imitate a fault status.
The ELCB should be able to trip or shut the power supply off at this instance.
This indicates that the ELCB device is properly working.
But if your device is not tripping or shutting the power supply off, it simply means that your ELCB is not functional.
How would you know if your ELCB is tripping?
To see if your ELCB device is doing its job, check your lights or appliances at home.
If your lights or home equipment automatically turns off, it means your ELCB is working.
For replacement or fixes, contact a professional to help you.
Yes, there are ELCB testers. They are typically referred to as GFCI or Ground Fault Circuit Interrupters.
ELCB testers are used to protect humans, assets, and properties from the risk of electrocution, electrical fires, and other hazards.
These testers are mandated by authorities to comply for the electrical code of practice, especially in the following areas:
To test for earth leakage, you can use a leakage current clamp meter.
The leakage current clamp meter is similar to electrical testing devices that measure load current.
Moreover, leakage current clamp meters are more sensitive than other testers.
This makes them ideal to measure currents below 5 mA (milliampere).
To measure earth leakage, place the leakage current clamp meter around the live conductors.
If there’s no earth leakage, the clamp meter will show a zero value on the screen.
ELCBs can keep tripping, even in normal situations, due to circuit overloads and worn-out wire insulators.
In some cases, the age of the circuit breaker is also a contributing factor to abnormal trippings.
A circuit breaker is broken when it has no power.
In some instances, a broken circuit breaker is also characterized by discoloration in the casing, which usually indicates overheating or burns.
Other reasons could be the circuit breakers have not been replaced for a long time or it is full of dirt.
An Earth Leakage Circuit Breaker (ELCB) is an important electrical device when it comes to preventing humans, animals, or assets from the risk of electrical shocks and fires.
To test your ELCB device, you must first ensure that the wire connections are properly installed.
For optimal safety, it’s best to seek professional assistance when installing, testing, or fixing your ELCBs at home.
