Bus Duct in a C1D2 location Square D power zone?

[RC Collins]

Hello,

I'm installing a 480V bus duct from a transformer to to a new A/B MCC; the building is pressurized. This is my first installation so I was looking at I-Line2 by Square D but it doesn't seem to be rated for hazardous location approved.

So, I'm looking at Power Zone by Square D and it states to contact the vendor, which I have but they have to get back to me. Thought I'd run it by you guys.

My general take on this is that the inside of a pressurized building is not a classified area, just as the inside of a pressurized cabinet is no longer classified, even if the cabinet is within a classified area.

Why does the bus duct need to be rated for Hazardous Location? I've always used non segregated metal enclosed bus duct for outdoor transformer to equipment inside buildings. I always thought the sandwich busduct was for commercial applications, where you need feeder taps and such.

You would have a hard time pressurizing the building if a bus duct is entering into it. Lot of air/energy loss throughout the years. You probably want to use tray cable with sealed cable transit entry through the wall into the building.
