So I should start this by saying there is alot I don't know about electrical work so please excuse my ignorance. That being said I find myself stuck trying to mount some electrical boxes and having a clear path at the next box. Don't believe I will have enough room to bend an offset in 3/4 EMT on each side of the box. Anyone ever seen a spacer similar to this in photo?? The best I've came up with is a piece of uni strut screwed to wall girt/tin and the mount box to it. But at 40-50 boxes total thats alot of work.

I am not a electrician but i did stay home last night. I think they electrical box spacers. Somebody just put it on the back of the box to set it out. But google electrical box spacer you will see them. hope this helps'

I have seen the box extension I think your referring to, think they just turned one around backwards and shot the screws through both?
 
Guess I'm a hack, I woulda just but a block behind it.

They make boxes for that...

Elevated knockouts on the sides so that conduit mounted on the ribs (running horizontally) will go straight in.

Did you use those on your building?
 
Echo above, they used a box extension as a spacer.

How high do the metal panels run inside you building? In my shop they go up to the second z purlin maybe 8' high. The top of that purlin is open and makes a nice trough. We ran our electrical hidden in that purlin and it pops over the top and runs close to the wall into the top of the outlet boxes. Imo, it looks a lot cleaner hugging the panel vertical than if it were running horizontal along the raised portions of the panels

My panels are approximately 8' also. Have any photos of what you talking about? I think I can picture what your talking about but a photo or two would be great.

I only ran conduit for my welder wires, the rest we used 12ga armored cable. Some people don't like it, but if run and terminated properly it works fine. I've had more problems with wires getting nicked being pulled in emt than I have with the coil wire stuff.

If you insist on running it horizontal they make a box for that:

Commonly called (by my guys) a "core steel deep J"...you aint getting them at Lowes or HD I suspect but Mayer, City or your preferred local E wholesaler can help you out. That $10 price in the link is laughable.

Id run it vertically as suggested just for better long term durability.

@awheelterd wheel turd you fail with your MC cable exposed to physical damage. :D

When I shopped around, Zoro was cheapest I found. Had to buy 25, at about 4.50 each.
 
One way or the other I'm spending $ buying parts and pieces. If I run on top of the Z girt and then drop in vertically, I'll be using a TEE and possibly an LB to make the turn up and over the tin. Other way is buying the expensive boxes and going horizontally, which I'll still have to go over ,up, around a column , back down and over some more. :dumbass:

I wouldnt use an LB, If it were me (and you could make the argument this isnt 100% kosher) but Ive seen it done and inspected and passed - thats all Im going to say about that.
I'd mount a standard box at the top of the tin, half on half off, and run the conduit just above the tin line box to box. Supporting the conduit between boxes is the challenge. Several ways to accomplish

What's your thoughts on supporting conduit or attaching to tin?

Thank you for the responses everyone.
