OMG, I didn't know what I was getting into when I choose to use 2/2/2/4 cu for the feeder of this sub-panel. It took me well over an hour to simply connect 4 wires to the panel. Here's the current results (a pair of breakers are shown already installed to insure I had clearance attaching the neutral).

I should be able to meet the 12" rule by finding some way to attach the cable comming out of the sub-panel to the ocx/stud behind the panel. Not sure how yet as the wire is wedged into the corner from the "spring" effect of making that U bend. Since there isn't any room to get any sort of staple behind the cable to attach it to the 2x4 stud on its left, I guess I'll need to staple it to the OSB panel.

I'm feeling pretty good about being able to get the other end of the cable into the main box. The entry point on the main box is right inline with the 1x3 you see at the bottom of the image. I'll be able to secure the cable to the 1x3 as well. Bends to the SE cable going under the sub-panel will go real smooth. I was able to cut the edge of the 1x3 to a 45 degree angle (you can see the fresh sanding marks in the picture) and there is another 45 degree cut on the back side of the bottom 2x4 supporting the sub-panel. The angles are really cutting down the pinch points on roughting the cable under the sub-panel.

Assuming I can find any suitable staples to secure the SE cable, about the only outstanding question I have in my mind is whether anything needs to be done to protect the cable through the U bend. It doesn't seem to need any protection just based on how big and stout that cable is. But it just seems odd having a cable capable of supplying so much power being within easy hand's reach. I guess once everthing gets wired up, I could find some way to cover all the wires comming out of the top with some sort of panelling... sort of making the top side of the sub-panel look flush mount... after the fact.

You could have taken that cable in from the bottom.
Are you covering the panel in any way?
Is that an outside wall?
If that was an outside wall, just a peice of scrap wood behind the cable to protect any nails from the outside, but that is not a code requirement.

I have been to homes that had new sidnig installed and the nails penetrated the jacket, but not the wires.

With the position of the lug nuts, I pretty much had to come in from the top. But I still have the option of flipping it over. Either way leaves me 6 knockouts for circuits out of the top/bottom. I might even have to flip it over because I want to lift it higher so that the branch feeders coming out the the box will be above eye level more like the original panel is.

Just with the door that came with it. Otherwise the plan is to keep this wall unfinished.

It's an outside wall, but the otherside is brick. So I don't see protection from the outside as being an issue. I was concerned about if protection from the inside was required. Exposed MN seems to be ok in an unfinished garage, but I didn't know if the same held for SE cable going to a sub panel.
