Yes, test the same way, it is just and RCD incorporated into a Switched Fused Spur. Double check polarity and ZS on load side of unit. Also prove your meter on another RCD. You may have a faulty unit.Evening chaps..
I have just fitted some downlights in a bathroom and needed to give them RCD protection as there was none. I fitted the following:
View attachment 23855
The test button works fine and the unit trips when a fault occurs (touching neutral to earth) but I cannot get the MFT to test it for trip times which I need for the MWC. Its a fairy decent MFT and I've never had any trouble with it testing RCD's before but I have never tested this sort of RCD before, it has always been in the CU. I make contact with the live/neutral/earth of something which the RCD is feeding, I get the little 'tick' on the MFT and then it just wont test.
Am I missing something simple here? Is this unit tested in the same way as you would an RCD in a CU?
Did you test on the outgoing terminals or at the end of the circuit?
Not when the OP has said this it isn'tIt's a perfectly valid question from a very helpful member
In addition to Howards post above ^^^^ Have you tested the ELI prior to fitting the RCD ?, because if the earth loop is high resistance/non-existent, the tester will inhibit the test if the CPC rises above a pre-set touch voltage, usually set @ 50V, some testers allow this to be set @ 25V, so check this too.

has any IR testing been carried out beforehand?...
check for neutal-earth fault...
