RCCB not tripping when test button is pressed - Schneider Electric

WebThe test button is to ensure that the electrical and mechanical elements of the RCCB are functioning. (ii) I Test: A test at (50%) of the rated tripping current of the RCCB for a period of two (2) seconds. This acts as a 'no trip' test and the RCCB must not trip. This is intended to verify that the RCCB is. not subject to tripping when spurious ... WebJan 26, 2024 · Both circuit conductors (supply and return) are run through a sensing coil; any imbalance of the currents means the magnetic field does not perfectly cancel. The device detects the imbalance and trips the contact. . When the term ELCB is used it usually means a voltage-operated device. Webto the standards [14,15] the RCD’s trip current may fall in the range of 0.5I û N - I û. This means that a functional RCD with a nominal differential tripping current of 30 mA (maximum permitted current to protect people from electric shock) can be tripped at 50% of the nominal current, i.e., at 15 mA.
