I think we're definitely going to have to 'agree to disagree' on this
Just to make sure I'm not doing you an injustice ... are you saying that a trailing socket lying on the floor, wired with flex that went through a hole in a shelf to a plug that was plugged into a wall mounted socket would be 'acceptable', whereas it would
not be acceptable if, rather than having a plug on it's end, the flex was 'hard-wired' into a wall-mounted FCU, switch, outlet plate, connector block/Wagos (behind blank plate) etc. etc. ... and that, given that you have cited 134.1.1, you would actually give a C3 to the latter?
