RCDs and the Importance of the Test Button.

stakes are for pinning apprentices to the workplace.

They're things you plant in the garden aren't they?
Stakes I mean, not apprentices.

This rcd fail issue is a clear explanation as to why relying on Rcd's is fundamentally wrong, the things should be banished, a better approach needs to be sort. RCDs only give a false sense of security. The manufacturers would dissolve all responsibility as they would say that their instructions had not been followed.
Whilst I agree that after several manual trips the things work within specified parameters, they should be replaced. Perhaps the manufactures should employ quarterly rcd testers. Either that or every one that fails should be returned for a free replacement.

why are we not told to at least put down mcbs every now and again as they can be up for years also

agreed....if you cant get a compliant Zs without RCD then theres something wrong....i`v seen several previous schedule of tests now when on an ECR with 1667 scrawled down the loop boxes.....not acceptable to me as its supposed to be additional protection on TN...i wouldn`t accept it for fault on a TN....which is effectively what it`s doing if Zs hasn`t been met without it...

yes....
and how many customers ............. are shown functional operation on handover...

All of mine mate, whether they take any notice of it is another story

my old boss would run people through and then say right now you tell me how it works/what to do no one ever could

HI,
The Company I used to work for had us pressing the test buttons on RCD's on over 200 sites every 3 months ( as per manufacturers instructions ). Needless to say we integrated this with other maintenance work. Once a year we tested the tripping times of the RCD's and tested the button last. As Tel says they can get a bit 'sticky'.

Regards.

Ha I do this on a couple of sites...just walk round the site pressing the buttons, nice and easy...
