Hi
Would running nmc (approx. 6 #12 and 2 #10) on top of a basement wall below the floor joist be code compliant? The floor joist are sitting on a 2x6 plate and the basement wall is 10 inches thick. Could this be the same as using running boards? I have searched the 2005 code book but can't find anything that would support it
 
For what it's worth, I run cables up there all the time. The pressure treated sill plate is normally a 2x6 or 2x8 sitting on top of an 8" or 10" block wall. You have this 1-1/2" high space on top of the block wall to stash cables. I think this is a great place to run cables, if that is indeed what you're talking about:

Hi
Thanks for the replies. NMC I thought was non metalic cable or romex. Ive only been an electrician since 1962 so I'm still learning. I can use all the help I can get.

Thanks Charlie

Okay, I'll bite. Where did you get your hands on NMC cable?

NMC - Insulated conductors enclosed within an overall, corrosion resistant, nonmetallic jacket (from 334.2)

It is covered in the NEC but I have never heard of any wire manufacturers that actually make it.

I think the OP is referring to regular NM-B

If so then he has bundling problems.
 
Hi
Why would running the cables on top of the basement wall be a bundling problem and approx. 50 cables coming down the wall to the two 200 amp distribution panels not be? What article covers bundling; I have searched the 2005 NEC book and can?t find anything, maybe I should go stay a night at a Holiday Inn.
Thanks Charlie.

Bundling has been being enforced for last 6 to 10 years.I as probly others are wondering just when did you do your last home ?Many things have changed in the last 20.I have not none a house in last 5 years,ok one.Many things now that passed 10 years ago never fly now.We have afci,gfci,bundling.I myself fould find it hard to go wire a house monday without talking to a local residential guy.Go check how many conductors can be ran together in the charts,you might be in for a shock.

Hi. Welcome to the forum. Lots of guys around here call "romex" by the letters NMC and they mean Non Metallic Cable, but the "C" actually means "corrosion resistant". It's a common misnomer.
As far as "bundling", take a look at 310.15(B)(2)(a) in the NEC. :smile:

Hey sometimes I think I'm a misnomer,

I've never seen any new NMC. I've seen old, already installed, NMC. The old-timer that trained me called it "barn cable", because that's how it was mostly used. I really don't see how it was any different than UF.
