I'm planning to run two new 15 amp circuits from the basement up to the
second floor of our 36 year old house. These will be used for general
outlets and a future whole house fan. I've found a first floor wall I can
run it through, but the space between the studs currently has a metal
heating duct in it. There is enough space next to the duct, but is it
acceptable (and safe) to run standard romex along side a residential, forced
air heating duct? The wire wouldn't be attached to the duct, but it would
be within an inch or two, and probably touching it in several places. I
wouldn't think the temp would be a problem; it would be nowhere near the 90C
temp rating of the wire, but I wasn't sure if there might be any long term
effects on the wire. It would be along side it for about 10 feet.
Just to make it clear, I am NOT talking about running it inside the duct.
Any information would be appreciated.
