WebMar 20, 2024 · IF the cable conductors are 4 sq mm then that has a resistance of 0.0046 ohms per meter. As you cable run is 50 meter that is 100 meters of conductor so the total resistance of the cable is 0.0046 x 100 = 0.46 ohms. That would give a fault current into a short circuit of about 500 amps which should cause the MCB to trip very quickly. WebNov 11, 2024 · 3rd current – Further, the manufacturer of the RCCB breaker design the RCCB, which will trip faster than the above must-trip time. For a 30 mA current, the must-trip time is 500 mS. Then RCCB is designed to trip faster, just in 300 mS. (Fig 4). That is the reason “why 30 mA RCCB breaker is used”.
