    GENERAL NOTES ON ELECTRICAL SUBJECT

    1) Why ELCB can’t work if Neutral inputs of ELCB do not connect to ground? ELCB is used to detect earth leakage fault. Once the phase and neutral are connected in an ELCB, the current will flow through phase and that much current will have to return neutral so resultant current is zero. Once...
