AC Type RCD No PV or Car Charger C3 or C2

There's also the related question that arises because AC types aren't defined not to work with d.c. residual currents - merely that their performance is undefined - they might just happen to perform adequately. Some AC types certainly did behave more like A types and there's even been a suggestion that some real A type RCDs were marketed in the UK as AC types - because that's what buyers here expected (and it was easier/cheaper for the manufacturer to produce a single type, at a time when other parts of Europe were already insisting on A types).

So can you properly code something if you can't be sure the problem really exists in reality?
