(Hit send accidentally!). Ok, I'm attaching 2x3s to upper sides of joists (see photo) to be able to drywall in between exposed joists. I'll also be running Romex to light fixtures. Will I have a problem with stapling cables to center of 2x3 sides as regards NEC 300.4 (D) quoted below? Is it too close to subfloor above? I know you need to be 2" from top of joists if you drill through the joist and 1-1/4 from edge of a stud, but what about this application? Thanks! Rebecca

NEC 300.4 (D) Cables and Raceways Parallel to Framing Members and Furring Strips. In both exposed and concealed locations, where a cable- or raceway-type wiring method is installed parallel to framing members, such as joists, rafters, or studs, or is installed parallel to furring strips, the cable or raceway shall be installed and supported so that the nearest outside surface of the cable or raceway is not less than 32 mm (11?4 in.) from the nearest edge of the framing member or furring strips where nails or screws are likely to penetrate. Where this distance cannot be maintained, the cable or raceway shall be protected from penetration by nails or screws by a steel plate, sleeve, or equivalent at least 1.6 mm (1?16 in.) thick.
