basement wiring?
 
I'm running wiring between joists in the basement, but when I cross 1 or 2 joists there are round heat ducts in the way, should I run the wiring on top of the heat ducts or below it?

Does it matter?

Whichever is easiest for you!

Does not matter AFAIK
 
I don't think it matters. I like to run below because it is easier.

Run the wire to the side of the ductiong that will give you the most clearance from a nail. If you are putting down hardwood floors upstairs and can't get more than about 3/4" away from the subfloor in ALL places that the wire will travel, run it underneath. There are a lot of nails in flooring and pose too many chances of piercing a wire.

My thoughts about running it on TOP of the ductwork is this: when the heat is on and that duct warms up, the warm air is going to rise, creating a higher temp above it than below it, and if there are cables up there it will make the ambient temp higher. I am not saying it will get above 75*c, but it wil be significantly warner. How many cables and how close they are could also be a factor.

I generally stay below this way if you ever replace the floor it will less likely get hit, and I drill the holes at a angle so its easier to pull the wire.
