The label is acurate, if misleading. It does say "ETL Listed Attachment Plugs and Receptacles", which I take to mean the plug and the receptacles are listed as individual items, and that seems pretty reasonable.
However, what it does not say is that the entire assembly is a listed unit.
I think it
is listed as a unit, but only to UL 498, which may not fully test the assembly.
It is a bit like the "surge suppressors" that were listed to UL 1363, but not UL 1449. It doesn't fully cover the complete product.
Who wants to bet it'll get stuck to one of the washers hose bibs with plumbers strapping if attached to anything?
Someone will decide the green wire is "in the way" and will cut it off.
