WebA previous post can be read for more details under the title of “Main Difference between Fuse and MCB and symbols used for Circuit Breakers, Fuses and Protection devices“. What is ELCB (Earth Leakage Circuit Breaker) ELCB stands for “Earth Leakage Circuit Breaker” and it is used for protecting a person from electric shock and injury ... WebThe first way of testing an earth leakage is to adopt an isolated power system (IPS). An IPS is typically combined with insulation monitoring devices that differentiate the imbalance between neutral and line conductors. The IPS method is a less frequently used method of conducting earth leakage testing.
