It's a straight pull, so why not take the conduit straight through the gutter box. Forget bothering with connectors. This is a quality contractor, is this quality work?

Well............This is one I'd like to see the IEEE do an arc fault test on, and I'm sure they meant to come back and weld it later, if they're under the 96 code where that type of thing was still allowed [Linked Image]

.........Do you have to count the conductors inside the pipe as gutter fill ? [Linked Image]

I doubt this would pass here.

I don't really see any problem with the installation as long as there is not a derating problem with the conductors in the large conduit between the wireway and the panel. It appears that the nipple may be less then 24" so that would not be problem. It would have been cheaper and easier to use a smaller wireway and install it in front of the large conduits that pass through the wireway in this installation. Is there a code violation here? I don't see one.

maybe there was a bid change? I have waited on panels to come in , and because of time I ran pipe anyway, BELIEVING the panel would be as specified.
This would work.
I wish I had a pic of the last hospital we did . It was awesome. the inspectors said they never seen a cleaner installation.

It seems obvious to me that they did this because they needed the trough space for the smaller conduits to terminate as the panel would not have enough room for all of them. Looks like an ok job to me,if not a little bit of an odd setup. Why would this not pass inspection?

I've done instillations that are similar to this before. I am a huge fan of using troughs and j-boxes to keep my penetrations into a back box at a minimum, especially in a very cramped electric room. I would rather set a few large runs of pipe into a panel from a trough than a ton of smaller runs, especially on a large job where you don't really know how well your guys can run pipe. Also, it's much easier to support four or five runs as apposed to twenty+ [Linked Image]

code 300-10 ...?

It appears to me that all the EMT tubing coming from the panel with the exception of the middle 2"EMT nipple pass directly thru the gutter box. I mean LOOK I DON'T SEE ANY CONNECTORS ON BOTTOM OF GUTTER BOX do you guys?

The 2"EMT enters the gutter box with a connector.I am assuming from there those circuits are taking off thru the various smaller pipes.

They obviously needed the top panel space for the larger pipes.I've seen this a hundred times.Except for pipes passing directly thru a gutter box as they appear to be doing!?

Without knowing the circumstances it's hard to second guess why they did it this way.

Hard to tell but I think we are being fooled here by poor photography. It looks to me that only the center 2in actually terminates into the gutter and is properly done with a connector. The other 4 1@1/2 may in fact be going behind the gutter all together. Note also that there are two levels of unistrut here. Is does look to me that the gutter is being soley supported by the conduits unless there are spacers with bolts behind it which I woudl guess there are.

Based on the rest of the job, I don't think this contractor would do something like butcher conduits through a gutter. The rest of it is just too neat and proper.

For the appearance of the installation, I do not see any violations.

Is the panel a Service or Sub-panel ?
If a Service, is 230.7 met, is the GEC installed correctly, are bonding bushing used, etc. ?

Are the rquired bushing installed ?

If EGC's are installed, are they the correct size ?

Was recently on such an installation. The outside appearance was great!, But inside, horrible.
