I note that there seems to be some increased focus by instrument manufacturers to facilitate the testing of the 6mA DC detection element integral in some AC charge points. You can also buy a rather expensive adaptor with testing ports If you don’t want to open the enclosure. One charge point manufacturer requires that you purchase their Bespoke tester before they will provide accreditation for OLEV. It doesn’t seem to do much and doesn’t work on other manufacturers chargers. Anyway, I digress, the question is whether the RDCDD needs site tested and what parameters should be met.
Wylex AFDDs carry out a self-test function when initially powered up, and the AFDD repeats this self-test function regularly. They also have a test button (just like an RCD or RCBO), which you can use during the initial verification or EICR. Model certificates now include AFDDs among the devices listed, with space for test results.
So how do we know if the button confirmed the operation of the AFDD and the RCD functions?
If it only confirms the operation of the AFDD function then testing the RCD function with a tester should be carried out every six months.
