Required support for wiring in walls?
I'm finishing a basement and have used 2x3 studs around the exterior room walls. I've got a half inch gap between the stud walls and the concrete basement walls... is it okay to run NM electrical lines in this gap (to avoid drilling holes in the studs and make routing them easier)? I'm sure I still need to staple the wires every 4 feet or so and it will be awkward to do so for the horizontal runs but is there any general rule against doing this?

If this is your preference then tapcon some scrap 2x3 to the concrete wall inbetween studs at 4 feet intervals or there abouts. Staple your nm to the scrap. You must fasten it every 4 or 4 1/2 feet to satisfy most inspectors.
Personnally I would just drill the center of the studs and put a metal nail plate on the face of each stud where the cable passes through. One of these.......

Perfectly OK to run behind the stud wall.
NEC 334.30 - Fasten every four and a half feet and within 12 inches of boxes. If you are running behind the studs, it is acceptable to use cable ties to secure the cable to the back of the stud.

What RobertWilber said.

Just to add - I did this with some coax and cat 5. I put a staple every so many feet, right at the back edge of the stud,
I then used wire ties to support the wire. Easy as pie.

Thanks guys... I'll try it and see how my inspections go.

You could always call your inspector and ask them...may save you a load of time up front. I do this all the time with my house building project...don't know, call and ask...most times I'm right, other times I was glad to have his input.
