Hi all,

Just back from an EICR where one of the RCDS was testing out at 0.0ms for the 1/2, 1 and 5 tests both ways, not had this problem before, can anyone shed any light?

Thanks in advance,

Loops

Not had it for all 6 measurements, when I have had it on isolated occassions I have assumed the trip time was quicker than the tester could actually measure (I assume your using a Fluke)
 
What type of RCD is it. Is your meter set for that type. Have you ramped it?
 
It's a 30mA RCD tested using a Fluke 1651b which has no ramp test, tested using correct settings, wired up and isolated same results, was thinking duff RCD but wanted to check to see if this has happened to anyone before?
 
The op still hasn't stated what TYPE of RCD it is.
 
Apologies, it is a Contactum 63A 30mA DP RCD in a domestic property -

Associated standards:
BS EN 61008


Rated voltage:
220-250V



Rated current:
63A

So if it's type B have you got your tester set to DC. Has it got the type B symbol below.
