WebRCCB is designed such way that it continuously senses and compares for difference (residual current value) in current values between the live and neutral wires. Any small change in the current value on account of such … WebSep 21, 2024 · RCCB will not guarantee to operate if load generates the standard waveforms. It is so because I CCV is designed to operate only on the supply of standard waveforms. It might be possible that there is some unwanted tripping of RCCB. It happens as there are specific changes in the electrical load. RCCB will not protect against current …
