Would like to here how others have in the past fed a surface mounted panel from a flush mounted panel in a single family dwelling?

I was thinking of coming into the back of the new panel but I'm concerned about the bending of the SER within a standard 2x4 1/2" drywalled wall.
 
Don't try it if the cable is cold (30f or less), the jacket will crack. It will work w/warm cable but might not be NEC compliant for bending radius. WE will see.

Just a shot in the dark...but...2-2-2-4 aluminum SER will bend in that space without hitting the minimum radius..The minimum inside radius is 2" on the #2 conductors (1.91" XHHW).

Why not use a 90 degree connector. The answer I just gave seems too simple. Did I miss something?
 
Ok why bring it into the back/within the wall cavity if surface mounted in the first place ????Why not sleeve the SER into the top of the panel.All other branch circuits will be done this way since it is surface mounted.
 
The panel I'm feeding from is flush mounted and is on the same wall. I'm putting this panel only about a bay or two away from the flush.

If I were to sleeve the SER how would you suggest I get the SER into the sleeve?

The ceiling is about 14 feet above the existing panel and the new for that matter.

I appreciate the replies and the suggestions.
 
How about flexible metallic conduit and a straight connector on one end and a 90 on the other, with individual conductors?

I recently used this setup in 1-1/4" to join a surface-mounted ATS to an in-wall panel. I'm sure you can get the parts up to at least 2".

The 90 degree connector must be accessible after it's installed.
 
I'd go for the #2 SER, a 90 amp breaker supplying it, inside the wall and turning into the back of the panel.

Not really.

I'd recess the panel, take the SER into the top and prep for more romex to be fished. Same difference, less to see. :)

If that wasn't an option, then I'd do what I outlined in the first sentence.
