please post the NEC section that aluminum wire must be coated with Noalox
i have never seen it, and i also have seen alot of bare aluminum.
as you said alot of interesting comments on here
I didn't actually state it's in the NEC. It may not be in the NEC (as far as I know), but it's definitely common trade practice with commercial electricians, at least with the ones I used to work with. It's just good practice. I know inspectors definitely like to see it used and I've personally seen them insist on it.
Here's a link to an electrical contractor's website that talks about it.Noalox discussion
