The basement ceiling is open so the joists are exposed. I need to run the wires through about 8 of the joists. But there is a fresh air intake for the HVAC system that crosses the path. So I was going to use conduit to run the wires in.
But I'm wondering if drilling out 2" diameter holes in the joists will weaken them and possibly cause structural damage?
What type of conduit should I use?
How close can HDMI cable be to electrical wires?
