Initially, the earth leakage circuit breaker were voltage detection devices, now they are switched to current sensing devices. The current ELCB is renamed as RCCB or RCD while the voltage ELCBs are still known as ELCB but they are obsolete. In this article, we are going to discuss ELCB in detail with both types. What is Earth Leakage?
Earth leakage protection devices are crucial for electrical safety, preventing electric shocks and fires caused by faulty wiring or insulation failures. Three common devices used for this purpose are Earth Leakage Circuit Breakers (ELCBs), Residual Current Devices (RCDs), and Residual Current Circuit Breakers with Overcurrent Protection (RCBOs).
Earth leakage current is not specifically defined in BS 7671:2018+A1:2020, it is referred to as protective conductor current. Protective conductor current is defined as an ‘ electric current appearing in a protective conductor, such as leakage current or electric current resulting from an insulation fault.’
The electrical current that flows from the live conductor to the earth through an unintended path is called earth leakage. It may flow between their poor insulation or through a person’s body and cause electrical shock. The consequence of electrical shock may prove fatal if the leakage current exceeds the only 30mA.
Maximum values of earth leakage for appliances are identified below, it is important to remember these are maximum values: For class II appliances and for parts of class II construction - 0.25 mA. For class 0, 0I and III appliances: 0.5 mA b for class I portable appliances -, 0.75 mA. For class I fixed motor-operated appliances - 3.5 mA.
Earth leakage current can exist through an insulation fault in cables or equipment, or it can occur under normal operating conditions in electronic equipment which use capacitors for filtering purposes in power supplies which can cause leakage to Earth when functioning.
