rcd tripping

[holsten19]

Has anyone found the rcd tripping even when on no trip on a new circuit. Cannot find a fault on the circuit. Tried on another socket circuit in the premises & that tripped as well.

Not clear what you're saying. Do you mean: the RCD trips in response to a Zs test, even when on no-trip setting?

Is this a rcbo consumer unit ?
