I have an older style Generac 12 circuit ATS paired with a 15kw generator.

My main panel is recessed mounted in the garage with the entire top of the panel is occupied from circuits and the service being ran through there.  Studs on each side of the panel.

In order to get my utility power and chosen circuits to the ATS, I need to come out of the large knockout at the bottom.

Does anyone have any ideas (or pictures) of installations that look clean for doing this?

The ATS sits approx. 7" out from the wall with the bottom knockout 5" oc.  

What I have seen is most run the whip into the drywall and just fire caulk around it.  Not too crazy about that 

This is a finished sheet rock garage.  Not opposed to doing sheetrock work if need be.

I think a whip to an LB or Whip to a 6x6x4 PVC box mounted below the main then conduit from the LB or Box to the main panel is how I will do it.  

Wanting to hear other opinions before I move forward.


Thanks!

Here is how my sparky did it:

That picture is pretty. I'm just not sure that conduit is to code with all the wire necessary for a 12 circuit transfer switch

Gray,

Any chance you could take a picture from a little further back?

Thanks!

Of course it is not large enough, and that is because I had a brain fade. It is not for the generator, it is my RV connection. How numb of me.

I apologize; as I mentioned, for some reason (old😬) I conflated the RV receptacle wiring and a generator discussion. The photo is my RV hookup.
Nonetheless, with the properly sized components, it might still be a viable method. Here is a photo showing the entire panel, and how the wiring transits the wall to outside.

Is the wall cavity on either side of the existing panel empty? If so you can recess the ATS into the adjacent cavity and put nipples through the studs between the two boxes. The ATS will stick out from the wall a bit but it results in a clean installation.

This is the exact same way i do all my installs. i use a 2" piece of continuous threaded plastic nipple (schedule 80) between boxes to eliminate bonding issues. It makes for a very clean install. Just eliminate the prewired steel flex pigtail all together.
