An elcb is a specific type of latching relay that has a structures incoming mains power associated through its switching contacts so that the circuit breaker detaches the power in an unsafe conditionthe elcb notices fault currents of human or animal to the earth wire in the connection it guards. Means it detects the earth leakage current and.
Current Through Protective Earthing Electrical Engineering
Elcb wiring diagram. Today we are going to know proper rccb connection diagram with mcbif you do not know the connection of rccb then this article will be helpful for you. If any current leaks from any electrical installation there must be any insulation failure in the electrical circuit it must be properly detected and prevented otherwise there may be a high chance of electrical shock if anyone touches the installationan earth leakage circuit breaker does it efficiently. The elcb detects fault currents from live to the earth ground wire within the installation it protects. Circuit diagram using transistors. Earth leakage circuit breaker or elcb. A simple elcb circuit is discussed here.
A voltage sensing elcb does not sense fault currents from live to any other earthed body. If sufficient voltage appears across the elcbs sense coil it will switch off the power and remain off until manually reset. A short circuit hazard is visible and mostly tackled through a fuse or a circuit breaker unit.

A leaking current through earth terminal is probably more dangerous than a short circuit in a domestic wiring. There are many electrical engineering students and many other people who work in electrical wiring have some confusion about the selection of rating of circuit breakers and also the connection of rccb and mcb.
If ample voltage seems across the elcbs sense coil it will turn off the power and remain.
