button connects a resistive load between the line conductor on the load-side of theRCDand the supply neutral. The test circuit is designed to pass current in excess of the tripping current of the RCD to simulate an out-of-balance condition. Operation of the test button verifies that the RCD...
Residual current circuit breakeris sometimes also referred as residual current device (RCD) when we consider the device by disassociating the circuit breaker attached toRCCB. That means, the entire parts ofRCCBexceptcircuit breakerare referred as RCD....
Difference between ELCB and RCCB. ELCB is the old name and often refers to voltage operated devices that are no longer available and it is advised you replace them if you find one. RCCB or RCD is the new name that specifies current operated (hence the new name to distinguish from voltage...
