In my opinion, using the form "Romex®" feels a bit like advertising. Because of this, I would lean towards using the generic term instead.
Secondly, I think in most cases folks are not specifically talking about the Romex® brand of cable. Instead they are asking about nonmetallic sheathed cable in general. So I don't think there's any danger in changing a postspost's intent, by replacing "romex""Romex" with "nonmetallic sheathed cable" (or similar).
Nonmetallic sheathed cable can be referred to also as
- Nonmetallic cable
- Type NM cable
- Type NM
- Type NMBNM-B
- NM cable
- NMBNM-B cable
- NM
- NMBNM-B
