Earthing SELV LED driver.

Simon Barker: 
 

Hence the question “Is it me?” because I am not getting a grip on what the thinking is behind all of this.

Total lack of care, I would have said.  If it's Chinese, then earthing seems to be optional, regardless of whether the components actually have earth connectors.

There are a number of countries that some companies send their staff to [well, used to, back when we used to travel] accompanied with plug-in “socket-checkers” for this reason. I don't think it's fair to single out a specific one … although I'm not arguing too strongly.
