Tight Square Turn (90 degree) For EMT Conduit

[sberry]

I got 6k SQ ft, twice have I had to run a 25 ft cord across the floor because I needed more 120v, once for an extra 500 watt quartz light when painting a 10 yard dump truck and once for a wedding reception to add an extra coffee pot and that could have head done anyway. Over 20 years.
Only other times I really see need additions they didn't follow that path anyway and needed additional or remod.
I may have lied here, its possible I added a circuit to a pipe for a chop saw once come to think of it. But it was semi planned and in a way different type of building across 60 ft of wall.
Since had 2 gfci installed. 3 pipes you cant see out the back of this box.

As mentioned on a different post, I may overthink things. I was really seeing if there was any other options.
The lower left is with the dual 45's or compound 90 (I think).
The orange square metal would be the back right leg. The front right leg would be down the tape and the left legs would be down the conduit side. So the shelves will have the corner notched and the leg. Then the back would be hanging off about 9". All sounds like no big deal, but I was trying to keep the shelf depth at 2'. So 24"-9" leaves 13" between edges. I just worried how stable it would be. I was going with 2' because 4' is too wide and I did not want to waste 4 x8 sheet of plywood. I say all this to show there is a reason to my madness.

The other two pictures is me trying the 90. The radius is just too big. When I tried to pull it up parallel it was actually trying to bend the metal outside. It was worth the stick to learn. That what this is all about.

What I was saying earlier earlier is move the 45 out further so the leg can go in between the 45 and the building.

Not sure if you get this, but the photo on the LOWER RIGHT shows a right bend, tight into that corner and now headed straight down the corner...

Imagine another piece of conduit coming towards this corner from the adjacent wall.... but 12 inches lower, with a 90 sweeping up. Run this conduit into the other one coming down. Yes, you will no longer be on the purlin, but when you get to the next box, just turn up and into the box. Might need to support the emt in the middle, or run it down or up to the next purlin.

You could go down the corner, to the lowest purlin, then come across this purlin to the next box, then up, with an offset to get off the plane of 'inside the purlin' to now 'out where the box is'


Nobody realized the shelf has a principal steel member that cannot be notched.

Oh, a clarification- that surface looks 'puffy'... is it jsut a vapor barrier and then your exterior steel??? If so, yeah- no-go

If you simply want to move the orange leg back then use a 90 turned right in front of the corner then bend an offset to bring the conduit back so it is under the channel, doing it this way you should be able to get the orange shelf leg pretty much the thickness of the conduit away from the corner post.

There's plenty of give in that insulation.

not the insulation I was worried about - it is the siding.

Penright has posted a nice pic of that issue today.

Read post #1 again.
OP said he didn't like that method so he is looking for alternatives b/c going tight to the column keeps the shelves away from the corner/wall.

What, I have to actually read the entire posts now?!

In that case, now that I understand the issue, brewchief has the right approach.
