tripping times?

[Silly Sausage]

I believe it changed from 200 to 300 when it went from 16th to 17th edition, for 61008 and 61009 at least.

Could be right there.
I always thought it was 40ms @ 5x because that's a fifth of 200. 300 is just confusing!

It depends on the BS number. GN3, BGB and OSG has all the info needed

If we stick to the 200ms, least we'll be edging on the safe side. Though I can't recall seeing one above 54ms in my limited time of being let loose with an MFT (and that turned out to be my winky connections!).

I tested 2 Hager 30mA RCD's on Friday and 1x= 115ms on both RCD.

The 40ms at 5x stayed the same, don't understand why they changed the 1x to 300 really anyway as its not 5x40 which made made sense before.....the 5x test is the only one it has to pass anyway I seem to recall, although I would be changing the Rcd if it failed 1x anyway
i also have had over 100ms trip times before on one side of the cycle usually.

Aye, fifth of an Amp, you're into dangerous territory, <<40ms the better!

With any luck, Professor Cockburn will be along soon to enlighten us all further.
