Default RCD test button not tripping the RCD.

In article .
com, Rednadnerb scribeth thus
Hi all
After working OK since it was installed a couple of months ago the RCD
started tripping whenever anything was switched on.
After failing to isolate the problem by disconnecting circuits we (the
installer and I) realised that the RCD test button doesn't work, so
after a quick dash to Screwfix we got an identical one and installed
it but it's exactly the same! pressing the yellow test button does
nothing. Could it be we have two faulty RCD's or is there something
we're obviously missing?


I might be wrong but you haven't got the input and output's reversed?.

Or a Neutral to Earth short?...
