Electrical Cables Through Joists
Posted by Bobby on May 7th, 2008 01:41 AM
I need to run approx 15 electrical cables perpendicular to the joists in my basement. I am planning on drilling a hole in the center of the 2X10's approx 4" from the ends of the joists. The span is 12 feet. What is the largest size hole I can make without affecting structural integrity? Is it OK for me to put all of the cables through 1 hole? If not, what is the limit? Thanks Was this post helpful? Yes: or No:
