RCCB Breaker Tripping?

[lawrence101]

RCCB is an acronym of Residual Current Circuit Breaker. These devices are solely intended to detect imbalance between line and neutral. They will trip when current leakage to earth exceeds a set value, but will not trip due to overload - the devices downstream of it deal with overload.

I see . Would that be equivalent to a GFCB ( Gound fault circuit breaker ) here in Canada ?

I think over there you would call it a gfci which we call an (RCD) Residual Current Device or RCCB, an RCBO here is an (RCD) Residual Current Device with an mcb in one unit
