What is the diffrence between an ELCB(earth leakage circuit
breaker) and RCCB(residual current circuit breaker)?which
has higher degree of safety and why?
Answers were Sorted based on User's Feedback
ELCB is voltage based sensing device.If the leakage voltage is above 40 v(usually) it will trip.
RCCB is current based sensing devise. If the leakage current is above the stated amount it will trip.(U CAN BUY DIFFERENT VALUES from 5 milliamps to 300 milliamps)
RCCB has a higher level of safety because even if the leakage current did not get to the earth by the normal circuit maybe because the earth wire was not connected or loose but passed through somebody and than to the ground the rccb will still trip if the current is above the milliamp rating.
