Rcd not tripping and ramp test more than 30ma

If the test button doesn't work wouldn't you change the RCD? Personally, I would so that it can be tested by the end user.

Not just the end user - how would YOU be able to test it fully if the test button didn't work? Daz

I can plug an MFT in and do a ramp test. The end user can't. Therefore I can confirm that the RCD trips within the parameters of its design, but it would need replacing to check the device regularly.

Checking operation of the test button is one of YOUR essential tests of an RCD also though. Daz

Just a thought......and I'm no expert testing. If the installation meets the TN requirements (as stated earlier) i.e. disconnecting times are met then the RCD's if installed for additional protection , as daft as it may seem do not need testing.

The relevant regs here that state RCDs for additional protection must be tested, and how they are to be tested are 612.10, 612.13.1, and 415.1.1.
