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.
