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!

You ARE da man! I rarely see conduit work that takes on a new meaning of "craftsmanship"!
It looks like you evenly spaced all your KO's into the gutter! How long did that take?
Things like this kinda make me feel "green" again!

Nick, that is a very clean installation.

Do you buy gutter without knockouts and cut them in the field?

Bjarney,
Absolutely. I cant 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.

Great looking work Nick.

I could not agree more, any commercial / industrial equipment should come without KOs.

We try to get all we can without KOs but many times it is not a stock item.

Sometimes it is almost imposable to do a professional looking job because of the factory KOs.

Great stuff, Nick!
It's sure nice to see something like this after the poorly-planned installations I've run across.
The key is in the planning...The old "Measure twice, cut once".

Blank endwall panels and "-NK(no knockout)" wireways and boxes are worth any extra time and effort it takes to get them. There's not much use for those concentric KO's.

electure—I agree with you on the plague of concentric (and eccentric) KOs. Talking to switchgear-manufacturing engineers—they dislike them too, for ‘one-pass’ punches and dies are a constant headache to keep sharp on the production line.

This was done a few years ago so I don't remember exactly how long it took. It was done by myself and a JW. He did all the pipe you see in the photos. There is something in the pics I thought someone might pick up on and bust my chops for but it's probably not obvious because of the resolution of the pics. I have the answer but lets keep it interesting and see if someone can pick it out!
(Hint: The wall you see is 18 Gage steel studs and 5/8 drywall)
