Diagonal Wiring

I was reviewing my wiring book about common electrical code requirements and one statement is "do not run cables diagonally between framing members." Do the framing members mean studs and/or joists in an unfinished basement ceiling? Also, is there some reason, safety, etc. as to why diagonal wiring is not permitted?

Never heard the advice, don't know what book you're citing, don't know where you live, don't know whether this is meant to be a recommendation or requirement, and don't know the context of the advice. Please provide more information.

The book I found this in is titled "The Complete Guide to Home Wiring : A Comprehensive Manual, from Basic Repairs to Advanced Projects" from the Black & Decker Home Improvement Library Series. It was under common code requirements. I live in Blair, Nebraska. I am putting romex wires 12/2 through the joists in the unfinished basement ceiling.

I know of no electrical code that corresponds to what that book recommends, and I have never heard that recommendation before. I hope others can comment.

I'll guess the issue is practicality----it's obvious that it's much easier to bore holes "straight-thru" joists than at an angle, and angular boring would be done if the cable-run was diagonally across the joists in order to minimize the "friction" in pulling the cable thru the holes in the joists.

Q--- if you had to route 50 ft. of 6/3 cable thru holes bored in joists, how would you procede in boring the holes?

I just completed the task of pulling 6/3 cable to a new sub-panel. My recommendation is the measure carefully for each hole you drill. Measure both across and down. I used a template for my drilling. You want all the holes in alignment. Pulling 6/3 is a real b***h. If the holes are not square and in exact alignment you are in for some fun. Also if possible, try to fully unwind the cable before starting the pull; again it will be much easier if there are no kinks in the cable.

About the diagonal cabling, I would not do it, looks so bad. It also does not allow you to take advantage of running the cable between the joists, whereby saving some drill holes.

Before we get too far discussing 6/3, I will remind you that isuras2 is pulling 12/2.

Maybe the reason the author{s} of the book took into consideration workmanship & how sloppy a job would look if romex was running at all different angles. Just my 2 bits.
