I'm going to ask you guys to give me your interpretation of a line in section 701. I should say that this is in Chicago code, not NEC, but I'm just looking for how you guys read this:

701.8 Location. Generator locations shall comply with the following:
...(4) transfer switches and their associated distribution shall not be located in the same room as the generator or service equipment.

OK, sounds simple enough, right? The generator room is seperated from the ATS room by a three hour wall (per code). All OCPD, ATS, and panelboards are in the ATS room.

The engineer is making noise that this section prohibits us from running the feeders through the generator room. Would that be the "associated distribution"? I'm not reading it like that but I'd like to hear what you guys think.

I'll be in touch with the AHJ early next week to see what he thinks.

"Normal" feeders? I would say NO, avoid the room.
Obviously the Gen feeders must get out of the source to the ats.

I didn't describe the feeders correctly. The conduits running through the room are actually the load side of the generator.

Well unless it's a wireless generator I don't see what other choices you'd have.

is the engineers last name Tesla, by chance?

is this as opposed to the line side of the generator:whistling2:

that would be a diesel or NG fuel line wouldn;t it?

transfer switch and their associated dist. The feed from the genset to the ATS is not "their associated distribution". It is the feeders to the ATS, obviously.

Since engineers are so smart, does he have a solution to you having to connect wires to the genset and place them in conduit without them being in the genset room?

Yes, I see the folly of my statement. But you're right, the feeders I'm referring to are the emergency connections. I'm hoping that the normal feeds still are not in the room. So many walls have changed places recently, it's hard to tell. Nothing on a print, mind you, just conversations.
