just a quick one doing some rcd tests today, and at x1 value the tripping time was 46mseconds and at x5 29mseconds now i no that as long as at x5 value is under 40mseconds all is ok just thought the x1 value was a bit high so my question is there a max value for times 1 as i must admit not had x1 values that high before your thoughts please
 
x1 should trip within 300mS. TN, or 200mS TT.
 
There all the same those switchy things than the wires go in. I only use the ones with 40 on them cause its my favourite number.
 
but if the wirral was in wales, would there be enough sheep to go round?

would the sheep need the wellies to cross the dee estuary?

What is the point of conducting tests if you do not know what constitutes a good or bad result?

I had my way the would be razor wire across the border and any bugger trying to get across it into England would be shot.

There again I could take solence in the fact I catch a Welshman inside Chester city walls after 6 at night I can legally kill him as long it is with a bow and arrow.

Wow that was intense

Its probably best now to have the cheques sent by post
 
I always found that hager boards that are around 10 - 15 years old, the 1x usually comes out at around 135ms, only ever seen it on these boards, and interestingly my hager board of the same era (2000) does exactly that, but the newer ones are 30 - 40ms.

I have to say I always make a note on the cert, although its perfectly acceptable and within, make a note that it's on the higher end of what I would like to see, but nothing needs to be done. I guess I just make a note on an observational level in case the next person questions it and has my paperwork to hand.
 
The dimmers I install used to have hager RCDs in them and they were always in the late hundreds for x1 trip times.

They use Eaton parts now since Eaton bought the company (cooper controls) that own the company (zero88) that manufacture them. Funnily enough zero88 are welsh! (As far as I know they still are)
