Beyond requirements of the NEC for certain products to be listed, there is a presumption of product safety if listed that is not there if the product has not been tested to a product standard.
Listing doesn't matter if product manufacturing QC is lax, product safety can be jeopardized, but if QC continues to be lax, the listing can be pulled.
That is how I write such things because I have been frustrated by reading content with unexplained acronyms. I am not a professional writer.That's the way to write it ... Write it completely out, then with the acronym in brackets. You must be a professional writer.
I agree, enforcement is always difficult, but it's not entirely out of the question, especially if you go after the producer/importer.Its based on my opinion that you can't really keep the junk out of the US and the only enforcement would be after the product has been placed into use.
If you can keep the junk out, that would be great, but I just don't see any such law being passed, or if passed, I don't see it being enforced at the import points.
