Circuit Breakers, a must!

November 23, 2009

After reading the newspaper the other day, I knew I just had to share this with you.

A Pakistani diplomat, died last month due to electrocution. The senior diplomat with Pakistan high commission died due to electric shock at his residence in south Delhi, while using a hairdryer.

“After taking a bath, he was drying hair using a dryer in the bathroom. He suffered electric shock,” a senior police officer said. The 47-year-old official, who was of a Brigadier rank, was rushed to Fortis Hospital in Vasant Vihar where he was declared brought dead.

This incident has drawn the attention of the Capital’s electricity regulator towards the need to enforce installation of the Earth Leakage circuit breaker (ELCB), also called Residual Current Circuit Breaker (RCCB) for all connections having a load of 5kW or more.

The RCCB is a safety device used in electrical installations to check earth leakage and prevent shock, detecting even a small current to earth (earth leakage) and disconnecting the equipment.

The Delhi Electrical Regulatory Commission in a recent order has asked the power distribution companies BYPL (BSES), BRPL (Bongaigaon Refinery and Petrochemical Limited) and NDPL (North Delhi Power Limited) to ensure that RCCB s for low voltage installations of 5kW and above are mandatory.

An RCCB not only checks wastage of electricity through leaks but also prevents accidents that can prove fatal. From the consumer’s point of view, an ELCB is a device that must be installed. There have been several instances where earth leakage has proved to be fatal.

An RCCB works by quickly detecting (within a few milliseconds) that a leakage has occurred, and disconnecting. This is a small enough time frame to prevent serious injury.

Did you know? Simple household appliances like a toaster, an iron or a mixer can turn into a death trap if there is an earth leakage. Do you believe that your family’s safety should be at the top of your priority list? If you do, you should immediately contact your electrician and install an RCCB or MCB at the earliest.

After all, safety is the most important factor, isn’t it?

    I have a 2 kilowatt meter I am interested in RCCB as there have been instances of getting shocks in my fridge and bathroom (during rains) I talked to my local electrician at Ghaziabad. At the first place he did not what an ELCB/RCCB is and then said there would be frequent tripping. I am confused Please suggest as I have a small Child.

      Hello Roy,

      You must place RCCB -30 mA for protection against electric shock. RCCB is a device which is specially designed for this purpose and protects you & your property from harmful current leakages if any exist in the electrical wiring. So, if there is leakage in the circuit RCCB should trip.

      To avoid frequent tripping problem get the wiring of your home checked for current leakages as well as proper earthing.
      But please install RCCB for the sake of safety; do not avoid it.

      The improper wiring and improper earthing leads to the standing current leakages which may result into electrical hazards.

    What is the difference between a Tripper, MCB, ELCB & RCCB.

    If they are not the same is there an equipment which combines all their Functionality?

    I have a tripper in my House, is it sufficient or should I have any of the additional gadget to be installed?

    regards

      Dear Uma Shankar,

      MCB is a Miniature circuit Breaker and it gives protection from overload & Short Circuit faults.

      ELCB (Earth Leakage Circuit Breaker ) & RCCB (Residual current Circuit Breaker ) is a device that detects current leakages & disconnects the supply if it goes beyond the harmful level. It provides protection from electrocution, fire hazards etc.

      There is no technical term as tripper used for the circuit breakers It may be the type of circuit breakers of some brand.

      You can use MCBs & RCCBs for the protection of your home. For right selection & installation of protection devices at your home consult an electrician.

        Elex,

        I came across this when I was looking for the difference between MCB and ELCB. I have bought a flat and the builder has provided MCB for the flat. I had got an electrician for getting all the electrical fittings done who suggested I should go for ELCB rather than MCB. The builder’s electrician stated that MCB is adequate for home. He also added that there will be an ELCB for the building as a whole.
        Have read through a couple of blogs and articles on the net including yours and I feel ELCB is better than MCB.
        However, would like to know if it is advisable to go for a ELCB for an individual house?
        If yes, any criteria you would recommend? (its a 3 BHK with all the standard gadgets thrown in) Please do suggest one of your products, if there are.

        Thanks in advance for the help.

        Dear Suresh Nayak,

        Thank you for taking the time and effort to reach us.
        Both MCB and ELCB are important to be installed in a house. There is a difference in both the products and they serve different objectives.
        An MCB prevents our electrical devices from getting damaged due to short circuit and overload where as an ELCB or RCCB prevents humans from any sort of electrical hazards/shocks which can be caused due to a leakage in current. We will be glad to assist you for any kind of future queries. Please feel free to contact us.

    At my house sometimes we get volt of 300 resulting in damage of all my equipments.
    Please advise if installing any of the product from havells can save my appliances in case voltage crosses 300 volts.
    Whether ELCB/RCCB will help ?
    Please advise.

      Hey Rajnish,

      To save your appliances from high voltage, I suggest you to install a voltage stabilizer. A voltage Stabilizer is an electrical regulator designed to automatically maintain a constant voltage level. Please revert back if you need any further clarification.

    Dear elex,
    We have just moved into our new home in gurgaon and we are facing problems regading surge of electricity, when the generator switches to the mains on resumption of power . The electrician has come in and connected made the neutral connection next to the contractor direct . I am not at all electrically aware, but am sure that the neutral serves some purpose and putting a small wire to make it direct ( whatever that means) cannot be a correct solution.

    This is happening far too often with consequential damage to my electrical gadgets.

    Need help on a few issues :

    a) Is there any professional electrical checking agency that one could contact to check the electricals in our place.
    b) Do we need to instal rccb’s / mccbs for greater protection.
    c) Any other suggestions !!

    Regards

    Dear Elex,

    We had at our residence havell’s C63 MCB installed. But despite this, many of the appliances were damaged yesterday. Our electrician says that MCB has now become defective. I am very confused. What is the point in installing Havell’s high cost MCB if it can go defective without any warning and causing huge loss. Can you please review and advise as to what could have gone wrong. Thanks and regards,
