RCD tripping while Zs

[rattlehead85]

We are talking about an MCB tripping here. Not the fact that we are using the no trip setting. The op was asking why an MCB was tripping, not an RCD. The no trip setting sends a reduced current around the circuit to prevent a sensitive rcd tripping during the test. If you refer to your literature or head over to the IET website this is explained.

I was responding to rmc86uk if you look back through the thread posts.
