I'm working on a plan to do electrical rough-in in a remodel and realized that it would be very convenient to bore a smallish (maybe only 1/2" - 5/8") hole in a set of tripled 2x4s under an LVL beam (thus making them a column, I assume).
I've read of course about being able to do a 40% bore on regular load bearing studs, but columns are not studs, and I've read that it's "not recommended" to bore them. I'll of course look at alternate routes, but I was wondering how common it is for people to pass inspections with smaller holes (not for DWV or pipes, etc., but just for romex) bored in regular columns, or even just king stud / jack studs around windows, e.g. (technically also a column, I gather).
Any advice on this, or could someone point me to relevant codes? I'm having a lot of trouble finding an authoritative source saying anything other than "not recommended" (which implies to me that it *can* be done, with certain restrictions, or maybe something like a Simpson stud shoe ).
Thanks.
