Promotion of Residual Current Circuit Breaker (RCCB)and 16A Wifi Smart Plug in association with Havells

To ensure safety of users against hazards of electric leakage, BSES Rajdhani Power Ltd (BRPL) joined hands with Havells India to strengthen the distribution of electrical protection devices in South and West Delhi and to drastically reduce the electricity related accidents which result in loss of life and property.

As per the DERC (Supply Code and Performance Standards) Regulations, 2017, it’s mandatory for all the consumers having sanctioned load of 2kW to have an ELCB installed at their premises.

1. What is ELCB?
Ans ELCB or Earth Leakage Circuit Breaker is a type of circuit breaker that is used for protection against leakage current. It breaks the circuit & disconnects the power supply to the load when it senses the leakage current. The earth leakage can cause electrical shocks that can be fatal. However, this is an old technology & is not in common use. RCCB being a current sensitive device have a better advantage over ELCB.
2. What is RCCB?
Ans The Residual Current Circuit breakers (RCCB) is basically an electrical wiring device that disconnects the circuit whenever there is leakage of current flow through the Human body or the current is not balanced between the phase conductor. It is the safest device to detect and trip against electrical leakage currents, thus ensuring protection against electric shock caused by direct contacts.
3. What are the benefits of RCCB?
Ans
  • Provides protection against earth fault as well as any leakage current.
  • Automatically disconnects the circuit when the rated sensitivity is exceeded.
  • Offers protection against voltage fluctuation as it includes a filtering device that guards against transient voltage levels.
4. What is meant by Sensitivity of RCCB?
Ans
  • A human being is able to sustain an electric shock to the extent of 30 mA.
  • While up to 10 mA may just evoke a prickling sensation, 10 mA onwards may lead to muscular contraction, further leading to a respiratory paralysis at around 30mA.
  • RCCBs are therefore designed to look for small changes in residual current.
5.

What are the different types of RCCB based on Poles?
Ans

RCCB is mainly classified into two types.

  • 2-Pole RCCB: It is used for protection in a single-phase system. It has 2 ingoing & 2 outgoing terminals having phase & neutral connections.
  • 4-Pole RCCB: It is used for protection in a four-wire three-phase system. 4 Pole RCCB is utilized in a 3-phase supply connection that includes a neutral wire and 3 phase wires.
