1AWG SER In Conduit?

[1.21 Gigawatts]

Hey guys... Running a 1AWG SER from Main panel in garage up to the attic and back down into the garage on the otherside and down to the basement for a subpanel.

I want to protect it in the garage. I noticed a 1.5" PVC "sleeve" will work but if I wanted to use an LB even a 2" seems very tight.

Can I (should I) do away from the LB and just do a sleeve? There would be an exposed part at the bottom of the garage wall though.

I'll have to ask if he wants to box it all out but wondering about the LB or another way to protect it

The issue with the LB will be the 5x bending radius in 338.24 and the rules in 314.28.

Wonder if a 90 would work

I agree with 1.21 use an elbow. For protection from physical damage you'll need Sch80 PVC.

A standard 1.5" 90 should have a radius not less than 8.25"

A piece of 4 x 4 trough. In the end and out the back. By whatever length you need

That might work but you would still have to ensure that the bend radius where it exits the back of the wireway is at least 5X the diameter of the SE cable.

is that romex in the round box at wall bottom?

Does having a removable cover Trump that requirement?

You could strip the sheath off, use a FA and connector and transition to pipe and wire wiring method.

No, if you do what electro suggested in post #10 then the 5X rule goes away.

Looks like old BX cable

You can box it in with 2x4 and plywood and just sleeve it thru the wall. Or use an elbow

You could also cut a notch about 1/3 of the conduit's circumference for about 6-8" of the conduit's length, leaving a window that the cable can curve out of and into the wall. From the front, it would look like the conduit just stops with the end open.

This is why I like using FMC and pulling wire. It's easy to just transition to EMT for a stretch like this.

Alternatively, put a 12x12 box (or two) and splice.

Price it out and you're looking at 3x the price. It's not a bad install your way it's great but way more in cost and the cheap guy will win on these

 

[letgomywago]

Look up SE Sill plate you can get one for 4/0 se cable that should butt up to 2 in pvc ok for 1/0 SER . Use a coupling and shoot to the attic.

Not for what I do and where I get my materials, no, it isn't that much of a price difference. Maybe 10% more, not more than doing boxes and splices. YMMV, obviously.

old BX but funny story about that box. It was a splice box that powered an old small panel in the basement. That bx you see ran into another box shown here and look what they had powering it all. SMH
