ELCB is an Earth Leakage Circuit Breaker which is the same as an RCCB - a Residual Current Circuit Breaker, also sometimes referred to as an RCD - Residual Current Device.

You also get RCBOs - Residual Current circuit Breaker with Overcurrent protection, which combine the RCCB and MCB functions into one package.

If your RCCB/ELCB has tripped, there are but two possibilities : 1) It tripped on an earth leakage current, or more precisely on an imbalance between the currents in phase and neutral conductors, or 2) The device is faulty.

Answer / abdul

RCCB means Residual Current circuit Breaker.
Means the residual ce=urrent flowing in the circuits gets
activated & thte potential difference causes it to trip

Answer / arjunbel

rccb elcb
reverse current circuit earth leakage circuit breaker
breaker

it will trip a circuit it will trip source when body
whenever reverse current of equipment receives current
flows towards source I.e. due to leakage it can be preset
during short circuit to a predefined value ranging
15-100 ma

If the capacitor bank is installed in switchyard say 132/22kv then on LT side say 22kv/0.433kv is it necessary to install capacitor bank for maintaining power factor. if pf is maintained on HT side then will that be maintained on LT side as well.if not then how&why??????/ please explain...........
