I want to run a length of about 7 feet of nm 16-4 vertically in a space where there is a hot/cold air duct. The cable will not be inside the duct, but rather beside it.
Is this up to code? If not what type of cable do i need to make the run..
I've already put the NM 16-4 run in there, but don't have any current going thru it yet.
Thanks for your replies.
EDIT: i'm running 14-2 !! not 16-4!
