In a 2x8 floor joist spanning 12ft what is the largest diameter hole you can drill through for conduit?
1/3 the size of the joist, so approximately 2 1/4 in.Keep the hole a min. of 2" from the top of the joist. If it's 2" exactly, put a nail guard on the top.Don't put the hole within 6" of another hole. don't put the hole within 4" of a notch.This of course all depends on the joist spacing 12"/16"/24"? And what the live load is anticipated? If it's a regular floor it's one thing, a monster tub is another.
How to run wire through joist?
Drill a hole large enough and pull the cable through. The hole must be 1-1/2" from the edge of the joist to prevent nails or drywall screws from penetrating the cable. If the hole is less than this distance, a nail plate must be installed over the edge of the joist so when the wall covering is added, a screw or nail can't penetrate the wire. Any hole drilled through a joist must be no more than a fifth of the depth of the joist and should be as near as possible to the centre of the joist. Holes bigger than 30mm are not recommended without specifically designed additional strengthening to the joist.
