Hi,
Thanks for all the replies. Here is a situation that you may want to consider;
subfloor installation in 10" X 12' X 2" wood, where two 1-1/2" holes are drilled in the center running for 12 feet parallel to each other. Consider a 1-6/3, 1-10/3, 4-12/2, 3-12/3 running through each hole..I would say that this needs to be spread out a little..
I can see the temptation to drill a couple holes instead of 5 or 6 1" holes, but a better installation would be to restrict the number of current carrying conductors to three per hole. I wonder if there is a difference for large holes vs small holes. You can easily get 10 cables through a 1-1/2" bored hole and if it runs for more than 24" parallel bundled together then I would derate the cables.
regards
mustang
