RCD Trip Time

[chloebear]

I think I know the answer to this one - but could do with some clarification.

30mA RCD trips out at 51.8mSec on 1 times test & 38.7 on 5x Test values seem high to me - Domestic installation. Repeated the test 3 times just to make sure. RCD probably 11 years old and, of course, never had the test button pressed.

fine at x1. just in the 40mSec. at x5. although the x5 seems a tad slow

All within, so all ok.

What brand of RCD was it? Wasn't a Pre-S MK 4293 by any chance?

Mem RCD from a Memera 2000 board

Had this a week or so ago with the same board. 5x was at a similar result.

Did the manual test button about 30 times and it dropped by quite a bit
