HD had 4 different box connectors. Cheap ones for NM, BX, and BX/AC, and an

The electrical clerk recommended the NM, but that didn't seem right. I was

Would code require the ones labeled MC, or would the BX have been adequate?
The clamps marked NM is solely for romex, not BX, because if you
compare it to a BX clamp, there is a stop preventing the cable from
going through. This is necessary on BX so the anti-short bushing
(little red plastic at the end) will not fall out. If you use BX on an
NM clamp, the anti-short bushing can fall out
