Will Rccb Trip on Overcurrent?

Limitations of RCCB
It's mainly because RCCB is designed to operate on normal supply waveforms. There might be some unwanted tripping of RCCB. ... RCCB does not protect from current overload. It has been designed to protect only when the live current and neutral current are different.

What causes RCCB to trip?

When there is a unbalance between current in phase and neutral, the RCCB will trip and it will disconnect the main power supply. So any fault or cause which makes unbalance in phase and neutral current can be a cause of RCCB frequently tripping.

Does RCCB protect from short circuit?

Since RCCB does not protect against short circuits, it does not have short-circuit withstand rating. It is highly recommended to use a short circuit protection device such as MCB or MCCB in series with RCCB.
