Is there any code-compliant way to plug a 12V power supply pod into an attic receptacle and
have the 12v wire run to a wall mounted device in the room below? The receptacle is close
enough to the device's location that the cord will easily reach. The device is up near the ceiling,
and we're trying to avoid running the power cord (or a track) up the wall, in plain sight.

Would this be considered a flexible cord under NEC 400 and therefore not allowed, even
though it's only 12V?

If we can't, we'll run Romex from the attic receptacle and install a receptacle for the pod. It
would just be neater (and easier) to use the attic receptacle.

Constructive ideas are always welcome.

What you have is a class 2, power limited circuit. In general, you
could run CL2 rated cable to connect the transformer to the load.
But I think that's assuming the equipment is listed to be used
that way. For example, if it was an alarm system, you would just
run CL2 cable from the transformer that plugs into a receptacle
to the alarm panel. You could run it through walls, between floors,
etc. But that transformer has terminals for connecting the wire,
the alarm panel has terminals, etc, ie, it's intended to be used
that way and listed for use that way. If you take something like
a router and cut the cable, put the power source in one location
connect it to the load, it's essentially the same, but IDK if it's
kosher because it's not listed to be used that way.
