What is the point of the RCD?

Pass on that one but they’ll trip if the police use their radios prior to raiding your grow room.

or if anyone has a spare one lying around ill test one, see how many faults i can make for it to detect and see how well it does (or doesnt)...

Watch the video on that link and note the plug/socket type, un-fused 16A Schuko.

The initial reason for AFDD’s was the protect appliance flexes (cords) from causing damage when connected to an un-fused 16A outlet (receptacle).

If we look to North America. In the main appliance cords don’t have a CPC, moreover they tend to use figure of eight cord which doesn’t have an outer protective serving. So you can plug your table lamp (maybe 1A) in to a 16A receptacle, just don’t ask about earthing!
