OK lets look it up together.

Start in 250-60(b) where you get the permission to use the "GROUNDED"
conductor. (That is the neutral).
250-60(c) further says that grounded conductor "is insulated" unless
it is SE cable originating at the service equipment.

The practical result of that is that you will be using 10-3 if you use
Romex and usually that will turn out being 10-3/wg. The ground wire
was either cut off or terminated in the box.

Not the pertinent section.

As noted, 338-3(b) is the subject paragraph allowing the previous
practice that was modified.


338 only applies to SE cable. We already determined SE cable was an
exception to the insulated grounded conductor rule.
It does not allow 10-2 romex.

That's so; see other response. That's the way the uninsulated connector could be used. _IF_ the installation used non-SE rated, that indeed would have been a violation.
