Running cable.....

I'm about to run 6 new circuits to my kitchen for outlets,and appliances. Stove is already done. I'll be goijng through my basement, and have to go through a whole house worth of joists. I'm off to rent my right angle drill, but wanted to know if there was a problem running all the 12/2 through one series of holes, or is there a limit on how many cables you can run in tandem.

Make two, or perhaps even three holes and keep the cables separated.

So I can group two or three, but not all 7 correct? Is there a hard limit?

How did you go from 6 cables in your original post to 7 in your last post?

You do not want to run too many cables through a hole because it forces you to make the hole larger. Too large a hole weakens the joist.

Further, there are issues about de-rating of cables based on how many run together. These rules could come into play if you run the cables together for a long enough run.

My belief is rather than push the issue, keep the cables separated.
