If running teck cable that has #2 aluminum wire in it, wouls 2" PVC work ok? I mean can I actually make the teck cable bend the 90 degrees through the 2" LB to get through the wall?

2/2/2/4 Teck Cable. What LB do I need?

NEC typically requires a minimum of 5x the cable o.d. Your cable is ~1.36" od.
Your side of the fence may vary.
You want to consider eliminating the LB if possible or use a jbox. I havent worked with Teck cable but it looks like the jacket is just as delicate as ac cable for tight bends.

why not transition from the teck underground and then go to pvc into the garage? like have your teck connector to a pvc ta to some pipe then a ninety then an lb?
should be able to turn a corner much tighter with just the wire then the metal jacket as well

The OP is in Canada, the NEC has no relevance there, just as the CEC has none here in the states.
Hence, the statement "Your side of the fence may vary."

Another thing I am considering for sure. Possibly terminate the teck cable at the PVC LB with a weathertight connector, then just continued through the LB with the wires, rather than the jacketed cable. The jacket appears to be the limiting factor when trying to make a bend through the LB.
Holy heck! So you would need a 7" LB then? That seems way overkill!
This is starting to look like a good way to go.
The numbers were only to explain the issue-assuming they are even the same requirement for Ca. There is no 7" conduit but even so, it wouldnt make sense.
Besides you would only be concerned with the bend radius created due to the depth of conduit body and inlet/outlet opening distance.
A jbox or transition from pvc to open teck is possible depending on location, subject to damage, code rquirements, etc.
It would be easier to describe a possible solution knowing the details of how/why you need the LB and what is/is not already installed.
I ran mine in 2" conduit that was poured into the concrete. it is merely a sleeve and the tek goes right into the breaker panel. I realize the OP cannot do this as the concrete is poured already, but can you run the cable in that overhang you mentioned?

Thats what I was thinking could have been a possibilty - just 90 up into the bottom of the panel and forget an LB all together. However, I dont know the application details so it could have been just a pipe dream. But appears that you do!
That appears to be option #3. Probably the cheapest, and easiest at this point. Possibly just drill through the overhang and run the cable up past the top of the breaker box, then loop back down into the top of it?
Your feeds have to be isolated from all branch circuits in Ca?
Any reason not to have the main in the bottom of panel?
my panel is installed with the main breaker (used as disconnect) is at the bottom of the panel . the feed comes into it at the bottom.
yes, the feed has to be isolated from the breakers, and no circuit can pass thru the feed section of the panel

The panel could easily be inverted, with the main at the bottom, but my long term plan is to have 2 separate 30 amp recepticals below the panel, so either way it will gave heavy cable coming out of both ends.
(I plan a welding plug inside, plus an RV plug outside)

Thx.
Is that true for all panel types - main and sub-panel?

I assume so. my house panel is that way .
