Detached garage sub panel - connection from outside to panel
 
Hello

I ran a 2" conduit for my detached garage subpanel and have an LB connection on the outside that I ran through the wall to the inside. My problem is that the sweeping 90 elbows are too big to fit in the 2x6 wall cavity so I thought I could buy some smaller ones (similar to plumbing PVC), but it seems they don't make anything that will work. The sub panel is mounted to the wall about 2 feet above the wall penetration. I should have thought ahead and penetrated the wall so it met up with the back of the panel, but I didn't think about it until I went to fit the sweeping 90 elbow and saw that it wasn't going to work.... oops!

I'm guessing it wouldn't pass inspection if I just run the wires (2-2-2-4 URD AL) to the panel and not have conduit the whole way inside. So it seems like I need a solution for conduit to do a 90 degree turn in 4-5 inches. Since this is going to be behind drywall I was thinking of using another LB connector and then making sure there's an access panel there just in case. Unless somebody has any better ideas?? I also have to do the same thing for the other end of the conduit, but there I couldn't have come in directly behind the box since the electrical meter is there so I would have ran into this problem anyways. Thanks in advance!!

Another LB and length of PVC with an adapter is the way I would go.

Can you LB directly into the back of the panel?

When my brother-in-law built his garage, the electrician did this. The LB on the inside is set in the wall. They put an access door in front of it.

Move outdoor LB up. Patch lower hole in wall.

Thanks for the replies everyone! I haven't finished it up yet, but picked up a few more LB's at the store today. I think I'll just route it along that way and make sure there's access to it. The basement one will have an access door anyways so no biggie for the garage too.

I don't use URD, but from what I've seen, I'm not sure URD is rated for indoor use. I could be wrong though.

Inspector seemed to think it was OK. It doesn't say URD on the cable, but that was the description when I bought it. I thought it stood for Underground Residential Distribution, but not positive. I saw somewhere that it's used for street lights as well.

The final solution I used was plugging the hole and re-running it directly to the back of the box. Ended up being the easiest solution and it's on the side of the garage right near a fence so nobody will see it. Thanks for the help!

URD is just slang for USE type cable and must follow article 338.

The page is messed up a little, but if you scroll down to almost the bottom, you will see this particular URD is not rated for indoor use.
