Home Electric Shock Protection - Your Elcb Is Not Enough

Home Electric Shock Protection - Your Elcb Is Not Enough

By:




Most home electrical installations have an ELCB of one type or the other installed at their electrical panels. Many electricity users also do check to make sure that the ELCB does work.

However, is the checking enough to make sure that the household members are protected from the electric shocks the ELCB is supposed to protect them from?

This aspect of the electric shock protection seems to have deceived many ordinary electricity users for a long time.

Checking the health of the ELCB is simple and you can do it easily. While the electricity is on (i.e. not during the mains blackout) just open the electric panel cover, locate the ELCB unit and the TEST push-button on it. The test push button will test whether the ELCB unit is working properly or not.

Then gently push the TEST push button on it. If it trips (i.e. the ON/OFF switch will snap and drop to the lower position. You can see the OFF label or symbol), then the ELCB is working properly.

Since the ELCB is working properly, then you are safe, right?

Wrong. The test facility provided on the home ELCB will only confirm the health of the ELCB unit, but that test does not confirm that the ELCB will trip when an electric shock hazard does occur. It is a really sad fact that all this while this misunderstanding has left many homes totally unprotected from the risk of electric shocks.

This brings us to the second requirement for the proper operation of a home shock protection system, which is the electrical grounding.

You can think of the ELCB as the brain for the shock protection, and the grounding as the backbone. Without a functional grounding, there is totally no protection against electrical shocks in your house.

An improperly grounded electrical system is a serious hazard in anywhere, not just at home. Unfortunately that is the most common violations of the electricity bylaws. This shows how prone people and companies are to overlook how important the electrical grounding is.

Check your home ELCB once a month if you can, and after every thunderstorm to make sure it is still working and not burned out by the lightning surge current.

However, the electrical grounding system must also be functioning for the shock protection system to work. The grounding needs to be checked annually, or every two or three years by a qualified electrician. However, it is best to have it checked by the home-owner regularly at shorter intervals to discover any faults that may have been caused by factors other than the natural degradations.

Just remember that a good working ELCB alone will not provide the protection from electric shocks.
