Evening ,

Started testing a job today where the rcbos test buttons dont operate the trip ,

Yet the rcbos trip fine when tested , In my eyes this is a fail ?

Just want to see what others feelings are ?

Cheers

Thats what i meant... (its late)
Hope you find out, cos i never have.
I've known it happen to about 5.
Also, some don't work on 1x Ian but do at 5x
Also, the test button can trip upstream too.
Needless to say - I dont specify them.

If the buttons not working I would give it a C2 fail as this prevents the user from doing the required quarterly checks on them.

If they fail on x1 or x5 this is a little more complicated to decide on. If the RCD is being used to provide protection against shock and forms part of the ADS (Automatic Disconnection of Supply) protection then I would give it a C1 and also issue a warning notice to the client. If the RCD is only providing ADDITIONAL protection (cables in walls, fire, equipment used by ordinary persons, sockets outdoors ,etc) then I would give it a C2 fail.

Hope this helps.

Cant really be a C1 , as its not immediately dangerous.
