EICR Code for working RCD with non-functioning test button

[Risteard]

just shows that it's important to test by pressing the --- on a regular basis. i still recommend shorter interlvals than 6 months. i have a feeling that the 6 month requirement came in as customers could synchronise it with resetting the clocks twice a year. another case of pandering to numpties above safety.

Six monthly is a common recommendation around the world. As you suggest when the clocks change is the logical time to do this. Although if the so-called EU has its way then it's hard to know when to recommend. Not too sure why we had the quarterly recommendation in the past.

Not too sure why we had the quarterly recommendation in the past.

For outdoor ones with a dedicated RCD, or plug adaptors, it was always a case of "test before use" so you have high confidence it is still working.

So presumably it started with a debate on how long between testing for board-mounted RCDs to gave acceptable fault detection given the move from dedicated outdoor sockets/adaptors to the widespread use of them on all domestic socket circuits. I have seen some RCDs that say test monthly, but that is just not going to be done, and other say "test regularly" but don't always say what that means (to give wriggle room in court?).
