Hi all

Have a problem with a Wylex 32A Type C RCBO that has tripped to a utility room and heating plant room to a west London mid terraced house.
It will not reset even with all loads removed. I tried swapping the line and neutral conductors to an adjacent same rated RCBO and the same happened. I tested the ring between L-N at the utility sockets and incoming spur to the plant room and was 0.42 ohms. I only had time for a quick look on xmas eve and will return on Monday to carry out further tests. But not having had many issues with RCBO's I need some advice on how to test these devices properly and what the possible causes could be. There is no history on this fault as the property is vacant and the problem miraculously appeared!

Cheers
 
Yes! very good point for all the readers, its debate and the fact we respond like we do is presidence to our experience and understanding and enjoy the debate, so don't get my responses as a challenge on your competence as its what this site is about but regarding this particular issue and the comment about 250v been sufficient Ill still stand ground as we went off the OP's particular query with the respective posts and that's why I got a bit deeper, and realise you also test at 500v and hence this is just a personal debate but with regard I'm trying to show the reason for 500v testing of IR.... If there exists even a 1% false positive testing at 250v then it justifies the use of 500v, most cable is rated 750v - 1000v so no reason at all as some posts do to suggest that 250v is acceptable ... I've laid my ground for my argument and in most you have technically agreed we me but still back up yourself for your own argument to which you now confuse me, yes as a percentage it may not be likely but the regulations for testing IR voltages exist because all what we debate has already been debate and agreed... PS drunk dot com.... apologise tommorow if this is BS lol ..

So just to cut to the chase, are you two now agreeing that your schlongs are both the same size??
