Question NM Cable in Conduit?

Can I use NM (Romex 12/2 w/ grnd. or 12/3 w/ grnd. ) cable in 1/2" EMT?

The conduit would protect a NM cable drop from approximately 6" below a wooden residential floor joist to an outlet box on a concrete block basement wall at about 48" above the floor. Would I still remain within the NEC conduit fill requirement using the above cables?

This technique seems to simplify the overall installation.

Comments appreciated,

Your installtion will be code compliant by leaving the jacket on the romex down to the EMT connetor on the box, and having an adapter that has a romex connector on one side and EMT connector on the other side. An alternative is to use a regular romex connector, reg. EMT connector, and thread them into a rigid coupling of the correct size. Be sure to put a grounding screw in the box, and bond it.

The plan you have is good, I commonly install surface mounted basement receptacles in EMT, and need to convert to and from romex periodically for a homerun or lighting run.

good luck,
