The current flow of electrical system is always very hazardous and involves high risks. Complacency in the part of the electrical enginee or wrong wire connection can lead to serious damage by way of electrical shock circuit. This can cause leakages in current. Earth leakages is a electrical hazard and may cause fatal damage by way of electrical shock circuit. This can be protected by way of residual current circuit breaker. It is otherwise known as ELCB.
