These are intended to complement the "Is there a better way" thread. I did this a few years ago and had the same dilemma. This was GE switchgear with all the branch panels for the space mounted inside the switchboard. The electrical plans called for the gutter and the engineer wanted it. (I found it to be a waste in this case because it isn't legal to use it for what they intended) As you can see I was very careful to keep the conduits over the area they needed to terminate. That doesn't always work out for the best on the other end so I ran everything on a double strut rack to help facilitate turning out to the home run location. Some of the cross sections of the gutter look pretty crowded but they don't exceed 30. It takes allot of planning and it's very tempting to just hit the gutter and go. However, I don't want to do all that work and then get called for it and have to eat the re work!

I can't figure out why they still sell gutters and pull boxes with concentric KO's any more. They are just in the way 95% of the time.
