SUMMARY
The discussion clarifies the distinction between an Earth Leakage Circuit Breaker (ELCB) and an Earth Fault Relay. The ELCB activates when there is an imbalance between the live conductor and the return path, providing user protection. In contrast, an Earth Fault Relay triggers in response to faults on the energized conductor, focusing on equipment protection. The transition from ELCB to Earth Fault Relay is necessary to enhance equipment safety and reliability.
