For the following, I have (nearly) concluded that the

I'm not aware if mixing of voltages is allowed in a duplex receptacle (I
suspect it is not, since wiring errors become more likely and segregation
of wiring
))

Whilst the link to the UL press release works
receptacle with
USB outlets in their listings for outlets.
In such cases, I suspect the USB portion requires no field wiring and that
the USB portion replaces one outlet from a duplex configured device. Is
this accurate?

Hi Peter et al,
Here
Good afternoon.
A cable supplier has mentioned that cables cannot bear the HAR marking
if they are not manufactured within an EU country. This seems to be
buried in HAR agreement documents that are out of my reach. Can anyone
confirm this?
Regards,
Peter L. Tarver
